Potential solution

To refactor the scripts in the 'packages' folder, we will follow the proposed changes for each file, focusing on code quality, performance optimization, integration with the package, and additional refinements such as error handling, testing, and documentation. The reasoning behind this approach is to ensure that the code is maintainable, efficient, and consistent with the rest of the package. We will also ensure that the code adheres to PEP 8 style guidelines and includes proper documentation for ease of use and future maintenance.

Code

For each file, we will apply the proposed changes. Below are examples of how to refactor some of the scripts based on the provided proposals:

Refactor water.py

# Modularization example: Extracting the apply_mask function
def apply_mask(image, mask):
    # Code to apply the mask to the image
    pass

# Removing redundant imports and dead code
import time  # Remove additional imports of time

# Consistent naming conventions
def display_instances(image, boxes, masks, class_ids, class_names):
    # Function code
    pass

# Performance optimization: Avoid global variables
def predict(model, image):
    # Function code without using global variables
    pass

# Integration with the package: Consistent API
def load_model(model_path):
    # Function code to load the model
    pass

# Documentation: Update README and add docstrings
"""
This module contains functions for water detection and image processing.
"""

Refactor zone_inondee.py

# Consistent function signatures
def fill_edge(image, edge_width=10):
    # Function code
    pass

# Performance optimization: Vectorization
def white_area_size(image):
    return np.count_nonzero(image == 255)

# Integration with the package: Modular design
from utils import read_image  # Assuming read_image is a shared utility function

# Specific refactoring steps: Refactor delete_frame_lines
def delete_frame_lines(image, edge_width=10):
    image[:edge_width, :] = 0
    image[-edge_width:, :] = 0
    image[:, :edge_width] = 0
    image[:, -edge_width:] = 0
    return image

Refactor TimeTransition.py

# Code quality improvements: Add docstrings and comments
def jpg_to_png(directory):
    """
    Converts JPG files in the directory to PNG files with timestamps.
    """
    # Function code
    pass

# Performance optimization: Efficient file handling
def time_to_timestamp(time_string):
    # Function code
    pass

# Integration with the package: Consistent API
def timestamp_to_time(timestamp):
    # Function code
    pass

# Additional refinements: Error handling
try:
    # Code that might raise an exception
except Exception as e:
    print(f"Error: {e}")

For the other files (zone_inondee_origine.py, voiture.py, Sobel.py, Threshold.py, TimeTransition_origine.py, voiture_origine.py, utils.py), similar refactoring steps will be applied based on the proposals provided. This includes improving function names, adding error handling, optimizing performance, and ensuring integration with the package. Each script will be tested individually and in combination with the rest of the package to ensure that the refactoring does not introduce any regressions.

Files used for this task:

Changes on packages/water.py

To refactor the `water.py` script, we should focus on improving code quality, optimizing performance, and ensuring it integrates well with the rest of the package. Here's a practical proposal to achieve these goals: 1. **Code Quality Improvements:** - **Modularization:** Break down the code into smaller, reusable functions or classes. For example, the `apply_mask`, `display_instances`, and `transparent_back` functions can be separated out and potentially reused in other scripts. - **Remove Redundant Code:** There are multiple imports of `time` and `sys.path.append` which can be cleaned up. - **Consistent Naming Conventions:** Ensure that variable and function names follow a consistent naming convention (e.g., `snake_case` for variables and functions). - **Remove Dead Code:** The `min_in_file`, `max_in_file`, `min_fichier`, and `max_fichier` functions do not seem to be used and can be removed if they are indeed not needed. - **Comments and Docstrings:** Add comments and docstrings to functions to explain their purpose, parameters, and return values. 2. **Performance Optimization:** - **Avoid Global Variables:** Refactor the code to pass variables as parameters to functions instead of using global variables. - **Efficient Image Processing:** Check if image processing steps can be optimized, for example, by using vectorized operations with NumPy instead of looping over pixels. - **Model Loading:** Ensure that the model is loaded only once if the script is called multiple times, to avoid unnecessary overhead. 3. **Integration with the Package:** - **Consistent API:** Make sure that the function signatures are consistent with other scripts in the package. - **Error Handling:** Add proper error handling to ensure that the script can gracefully handle unexpected inputs or failures. - **Unit Tests:** Write unit tests for the functions to ensure they work as expected and to facilitate integration with the rest of the package. 4. **Code Refactoring:** - **Refactor Large Functions:** The `predict` function is quite large and does multiple things. Break it down into smaller functions that each handle a specific task. - **Use Context Managers:** Use context managers (the `with` statement) for managing resources like files or sessions, which ensures that resources are properly released after their use. 5. **Code Style and Standards:** - **PEP 8 Compliance:** Ensure the code adheres to PEP 8 style guidelines for Python code. - **Type Annotations:** Add type annotations to function signatures to improve readability and facilitate static type checking. 6. **Documentation:** - **Update README:** Ensure that the README file or any relevant documentation is updated to reflect the changes made to the script. 7. **Version Control:** - **Commit Changes:** Use version control to commit changes incrementally, with clear commit messages that explain the changes made. By following this plan, we can refactor the `water.py` script to improve its maintainability, performance, and integration with the CCTV-Inundation-Detection package.

Changes on packages/zone_inondee.py

To refactor the `zone_inondee.py` script, we should focus on improving code quality, optimizing performance, and ensuring it integrates well with the rest of the package. Here is a practical proposal to achieve these goals: 1. **Code Quality Improvements:** - **Consistent Function Signatures:** Ensure all functions have consistent input parameters. For example, `fill_edge` and `max_min_area_rect` both take an `input_type` parameter, but `delete_frame_lines` does not. We should standardize this across all functions. - **Remove Redundant Code:** The `delete_frame_lines` function reads the image but then overwrites the image variable with the image data. This is unnecessary and can be simplified. - **Error Handling:** Add error handling for file operations and image processing steps to ensure the script doesn't crash unexpectedly. - **Use of Comments:** Improve comments to explain the purpose of functions and complex code blocks more clearly. - **Function Decomposition:** Break down complex functions into smaller, more manageable pieces that are easier to understand and test. 2. **Performance Optimization:** - **Vectorization:** Replace for-loops with vectorized operations where possible. For example, `white_area_size` can be optimized by using NumPy's vectorized operations to count white pixels. - **Avoid Repeated I/O:** Minimize the number of times an image is read from disk by passing image data directly between functions instead of file paths. - **In-Place Operations:** Use in-place operations where possible to reduce memory usage and improve performance. 3. **Integration with the Package:** - **Modular Design:** Ensure that functions are modular and can be easily called from other scripts within the package. - **Consistent File Handling:** Use a consistent method for reading and writing images across the package. - **Shared Utility Functions:** If there are common operations used by multiple scripts, consider moving them to `utils.py` and importing them as needed. 4. **Specific Refactoring Steps:** - **delete_frame_lines:** Simplify the function to avoid unnecessary image read and write operations. Use slicing to set the edge pixels to black. - **fill_edge:** Remove the `input_type` parameter and always assume the input is an image array. This simplifies the function signature and usage. - **white_area_size:** Use NumPy's `np.count_nonzero` to count white pixels instead of a double for-loop. - **max_min_area_rect:** Ensure that the function only processes image data and does not read from disk. - **sort_contours:** This function is fine as is, but ensure it is used consistently with other contour-related functions. - **count_lines:** Optimize the Hough Line Transform parameters for better performance. - **line_distance:** Remove the `input_type` parameter and correct the call to `count_lines` to pass the correct data type. After making these changes, thoroughly test the script to ensure that all functions work as expected and that the script integrates well with the rest of the package. Additionally, consider adding unit tests to validate the functionality of each function.

Changes on packages/TimeTransition.py

To refactor the `TimeTransition.py` script, we should focus on improving the code quality, optimizing performance, and ensuring it integrates well with the rest of the package. Here are some practical steps to achieve this: 1. **Code Quality Improvements:** - Add a docstring at the beginning of the script to explain the purpose and usage of the script. - Add comments to functions to explain what they do, their parameters, and their return values. - Ensure consistent naming conventions (e.g., `snake_case` for functions and variables). - Remove commented-out code that is not needed to reduce clutter. - Use more descriptive variable names instead of generic ones like `file_nom`. 2. **Performance Optimization:** - Check if there are any redundant operations that can be eliminated. - If the script is dealing with a large number of files, consider using more efficient file handling or libraries that can handle batch operations. 3. **Integration with the Package:** - Ensure that the script uses relative imports from the package if it needs to import other modules from the same package. - Make sure that the script does not have any side effects that could affect other modules in the package. - If the script is meant to be used as a module, ensure that it does not execute code when imported (only under `if __name__ == "__main__":`). 4. **Additional Refinements:** - Replace the hard-coded file extension in `JPGtoPNG()` with a variable or constant, and allow the function to handle different file types. - Consider adding error handling for file operations and date conversions to make the script more robust. - If the script is intended to be used as a command-line tool, implement argument parsing to handle input parameters more gracefully. Here's an example of how the refactored `TimeTransition.py` might start: ```python """ This module provides functions to convert between human-readable time strings and UNIX timestamps, and to rename image files based on their timestamp. """ import time import os def jpg_to_png(directory): """ Converts all JPG files in the specified directory to PNG files, renaming them with their UNIX timestamp. Parameters: - directory: The directory containing JPG files to be converted.

It also provides a clear interface for other scripts to use the functions provided.

Changes on packages/zone_inondee_origine.py

To refactor the `zone_inondee_origine.py` script, we should focus on improving code quality, optimizing performance, and ensuring it integrates well with the rest of the package. Here are some practical steps to achieve this: 1. **Code Quality Improvements:** - **Remove Unused Imports:** Clean up the import statements by removing any modules that are not used in the script. - **Consistent Commenting:** Ensure that comments are written in English and provide meaningful information about the code. Remove any unnecessary comments. - **Function Documentation:** Add docstrings to each function to explain what it does, its parameters, and its return value. - **Variable Naming:** Use descriptive variable names that follow the PEP 8 naming conventions. - **Error Handling:** Add error handling where appropriate to manage exceptions and provide useful feedback to the user. 2. **Performance Optimization:** - **Avoid Repetitive I/O Operations:** Minimize the number of times the script reads or writes to disk by keeping data in memory when possible. - **Vectorization:** Use NumPy's vectorized operations instead of loops where possible to improve performance. - **Use Efficient Algorithms:** Review the algorithms used and replace them with more efficient ones if available. 3. **Integration with the Package:** - **Modularize Code:** Break down the script into smaller, reusable modules that can be easily integrated with other parts of the package. - **Consistent API:** Ensure that the functions have a consistent API with the rest of the package. This includes parameter names, default values, and return types. - **Remove Redundant Code:** If there are functions that duplicate functionality found in other parts of the package, remove them and use the existing functions instead. 4. **Specific Refactoring Steps:** - **Refactor `del_frame_ligne` Function:** This function can be optimized by using slicing instead of nested loops to black out the edges of the image. - **Refactor `fill_edge` Function:** This function can be simplified by removing unused code and ensuring that the mask is correctly applied. - **Refactor `white_area_size` Function:** This function can be optimized by using NumPy's array operations instead of a double loop. - **Refactor `max_minAreaRect` Function:** This function can be optimized by using built-in functions from OpenCV to find the maximum area rectangle. - **Refactor `compute_size_minAreaRect` and `compute_area` Functions:** These functions should be reviewed for efficiency and clarity. - **Refactor `crosswalk_count` Function:** This function is quite complex and should be broken down into smaller, more manageable pieces. - **Refactor File Handling Functions:** The functions `min_in_file`, `max_in_file`, `min_fichier`, and `max_fichier` can be simplified and optimized to handle file operations more efficiently. 5. **Testing and Validation:** - **Unit Tests:** Write unit tests for each function to ensure they work as expected. - **Integration Tests:** Test the script as a whole to ensure it integrates well with the rest of the package. 6. **Code Formatting:** - **PEP 8 Compliance:** Ensure the entire script follows PEP 8 style guidelines for Python code. 7. **Version Control:** - **Commit Changes:** Use version control to commit changes incrementally, with clear and descriptive commit messages. By following these steps, the `zone_inondee_origine.py` script can be refactored to improve its maintainability, performance, and integration with the CCTV-Inundation-Detection package.

Changes on packages/voiture.py

To refactor the `voiture.py` script, we should focus on improving code quality, optimizing performance, and ensuring good integration with the rest of the package. Here's a practical proposal to achieve these goals: 1. **Code Quality Improvements:** - Remove redundant imports and duplicate code. - Use meaningful variable names and remove French comments or variables to maintain consistency in English. - Remove unnecessary comments and commented-out code. - Ensure PEP 8 compliance for better readability. - Remove `del` statements at the end of functions, as they are unnecessary and do not execute (since `return` precedes them). 2. **Performance Optimization:** - Avoid loading the model in every function call. Load it once and reuse it. - Minimize file I/O operations by caching results where possible. - Use vectorized operations with NumPy instead of loops where applicable. - Consider using a context manager for file operations to ensure proper resource management. 3. **Integration with the Package:** - Ensure that the script uses relative imports from the package instead of modifying the system path. - Make sure that the script's functions can be easily imported and used in other parts of the package. - If the script is meant to be used as a command-line tool, consider using `argparse` or similar to handle arguments. 4. **Refactoring Specific Code Blocks:** - The `mrcnn` function is too long and does multiple things. Break it down into smaller functions with single responsibilities (e.g., `apply_mask`, `display_instances`, `transparent_back`). - The `min_in_file` and `max_in_file` functions have similar code; consider creating a single function that can return both min and max using a single iteration. - The `transparent_back` function can be optimized by using array operations instead of looping over each pixel. 5. **Testing and Documentation:** - Write unit tests for each function to ensure they work as expected after refactoring. - Add docstrings to functions to explain their purpose, parameters, and return values. 6. **Version Control:** - Use version control (e.g., Git) to track changes and allow for easy rollback if needed. - Commit changes incrementally with clear messages describing what was changed. 7. **Continuous Integration:** - Set up continuous integration to run tests automatically when changes are made to the script. Here's an example of how you might refactor the `min_in_file` and `max_in_file` functions into a single function: ```python def min_max_in_file(router, file_extension='*.png'): min_file, max_file = None, None for file in glob.iglob(os.path.join(os.getcwd(), router, file_extension)): file_name = os.path.split(file)[1] if file_name.split(".")[0].isdigit(): file_number = int(file_name.split(".")[0]) if min_file is None or file_number < min_file: min_file = file_number if max_file is None or file_number > max_file: max_file = file_number return min_file, max_file ``` By following these steps, you should be able to refactor `voiture.py` to be cleaner, more efficient, and better integrated with the rest of the package.

Changes on packages/Sobel.py

To refactor the `Sobel.py` script, we should focus on improving the code quality, optimizing performance, and ensuring it integrates well with the rest of the package. Here's a practical proposal for refactoring this script: 1. **Improve Code Quality:** - Add a docstring to the `sobel` function to explain what it does, its parameters, and its return value. - Remove the hardcoded file paths in the commented-out section at the bottom of the script. - Use more descriptive variable names to improve readability. 2. **Optimize Performance:** - Check if the input image exists before attempting to read it to avoid unnecessary errors. - Consider adding error handling for file reading and writing operations. 3. **Integration:** - Ensure that the function parameters are consistent with other scripts in the package. - If the package has a common utility module for file operations, use that for reading and writing images. 4. **Additional Enhancements:** - Allow the function to work with different kernel sizes by adding an optional parameter. - Add an option to return the gradient image in memory instead of writing it to disk, which can be useful if this function is part of a larger image processing pipeline. Here's the refactored `Sobel.py` script: ```python #!/usr/bin/env python # coding: utf-8 import cv2 import os def sobel(input_path, output_path, kernel_size=3): """ Applies the Sobel operator to an input image and saves the result. Parameters: - input_path: str, path to the input image. - output_path: str, path to save the output image. - kernel_size: int, size of the Sobel kernel (default is 3). Returns: - None """ if not os.path.exists(input_path): raise FileNotFoundError(f"Input file {input_path} does not exist.") image = cv2.imread(input_path) if image is None: raise IOError(f"Could not read the image {input_path}.") grad_x = cv2.Sobel(image, ddepth=cv2.CV_64F, dx=1, dy=0, ksize=kernel_size) grad_y = cv2.Sobel(image, ddepth=cv2.CV_64F, dx=0, dy=1, ksize=kernel_size) # Subtract the y-gradient from the x-gradient gradient = cv2.subtract(grad_x, grad_y) gradient = cv2.convertScaleAbs(gradient) if not cv2.imwrite(output_path, gradient): raise IOError(f"Could not write the image {output_path}.") # Example usage: # sobel("path/to/input.png", "path/to/output.png") ``` This refactored script now includes error handling, improved readability, and additional functionality for kernel size customization. It also removes hardcoded paths, making it more flexible for use as a module within the package.

Changes on packages/Threshold.py

To refactor the `Threshold.py` script, we should focus on improving code quality, optimizing performance, and ensuring it integrates well with the rest of the package. Here are some practical steps to achieve this: 1. **Code Quality Improvements:** - Add a docstring to the `threshold` function to explain its purpose, parameters, and return value. - Use more descriptive variable names instead of `ret, threshold` to improve readability. - Handle exceptions where appropriate, for example, when reading or writing files. - Remove the commented-out code at the bottom or move it to a separate test function. 2. **Performance Optimization:** - Check if the image is read correctly after `cv2.imread` and handle any errors that may occur. - Consider checking if the input image is already in grayscale before applying the threshold to avoid unnecessary conversions. 3. **Integration with the Package:** - Ensure that the function parameters are consistent with other scripts in the package. - If the package has a common utility module for file operations, use that for reading and writing images. - If there are any common thresholds or grayscale degrees used across the package, consider defining them as constants in a shared module. 4. **Additional Refinements:** - If this script is meant to be used as both a module and a standalone script, add an `if __name__ == "__main__":` block to handle command-line arguments. - Add type hints to function parameters and return types for better code clarity and to assist with type checking. Here's an example of how the refactored `Threshold.py` might look: ```python #!/usr/bin/env python # coding: utf-8 import cv2 from typing import Optional def apply_threshold(image_path: str, threshold_value: int, max_value: int, output_path: str) -> Optional[bool]: """ Apply a binary threshold to an image and save the result. Parameters: - image_path: str, path to the input image - threshold_value: int, threshold value to apply - max_value: int, maximum value to use with the THRESH_BINARY thresholding - output_path: str, path to save the thresholded image Returns: - bool, True if the operation was successful, None otherwise """ try: img = cv2.imread(image_path, cv2.IMREAD_GRAYSCALE) if img is None: raise FileNotFoundError(f"Image not found at {image_path}") _, binary_image = cv2.threshold(img, threshold_value, max_value, cv2.THRESH_BINARY) cv2.imwrite(output_path, binary_image) return True except Exception as e: print(f"An error occurred: {e}") return None # If this script is run as a standalone program, process command-line arguments. if __name__ == "__main__": import sys if len(sys.argv) != 5: print("Usage: python Threshold.py ") sys.exit(1) image_path, threshold_value, max_value, output_path = sys.argv[1:] apply_threshold(image_path, int(threshold_value), int(max_value), output_path) ``` This refactored version includes error handling, command-line argument processing, type hints, and improved variable names. It also assumes that the input image is in grayscale; if this is not the case, additional logic may be needed to convert the image to grayscale before thresholding.

Changes on packages/TimeTransition_origine.py

To refactor the `TimeTransition_origine.py` script, we should focus on improving code quality, optimizing performance, and ensuring it integrates well with the rest of the package. Here's a practical proposal for refactoring this script: 1. **Code Quality Improvements:** - Remove commented-out code that is not needed for understanding the script's functionality. - Ensure consistent use of quotes for strings (choose either single or double quotes and stick with it throughout the script). - Add docstrings to functions to explain their purpose, parameters, and return values. - Use more descriptive variable names instead of generic ones like `Time` and `Timestamp`. - Handle potential exceptions that may occur during file operations or time conversions. 2. **Performance Optimization:** - If the script is used to process a large number of files or timestamps, consider using more efficient data structures or algorithms. - Avoid redundant conversions by caching results if the same conversion is performed multiple times. 3. **Integration with the Package:** - Ensure that the script's functions can be easily imported and used in other scripts within the package. - If the script shares functionality with other scripts in the package, consider creating a shared utility module to avoid code duplication. - Make sure that the script adheres to any established coding standards or conventions used in the package. 4. **Additional Refactoring Steps:** - Replace the `os.listdir` and `os.rename` operations with safer and more modern `pathlib` operations. - Ensure that the script is compatible with both Python 2 and Python 3 if necessary, or update it to use Python 3 syntax exclusively. - Add unit tests to verify the correctness of the time conversion functions. Here's an example of how the refactored `TimeTransition_origine.py` might look after applying some of these suggestions: ```python import time from pathlib import Path def convert_jpg_to_png(directory): """ Converts all JPG files in the specified directory to PNG files, renaming them with a timestamp. :param directory: The directory containing JPG files to convert. """ for file_path in Path(directory).glob("*.jpg"): timestamp = time_to_timestamp(file_path.stem) new_file_path = file_path.with_name(f"{timestamp}.png") file_path.rename(new_file_path) print(f"{file_path.stem} -> {timestamp}") def time_to_timestamp(time_string): """ Converts a time string to a Unix timestamp. :param time_string: The time string to convert. :return: The Unix timestamp. """ struct_time = time.strptime(time_string, "%Y-%m-%d_%Hh%M") return int(time.mktime(struct_time)) def timestamp_to_time(timestamp): """ Converts a Unix timestamp to a time string. :param timestamp: The Unix timestamp to convert. :return: The time string. """ t = time.localtime(int(timestamp)) return time.strftime("%Y-%m-%d_%Hh%M", t) if __name__ == "__main__": # Example usage: directory_name = "path_to_directory" convert_jpg_to_png(directory_name) example_timestamp = 1596990600 print(timestamp_to_time(example_timestamp)) ``` This refactored version includes improved function names, the removal of commented-out code, and the use of `pathlib` for file operations. It also provides a clear example of how to use the functions in the script.

Changes on packages/voiture_origine.py

To refactor the `voiture_origine.py` script, we should focus on improving code quality, optimizing performance, and ensuring it integrates well with the rest of the package. Here's a practical proposal for refactoring this script: 1. **Code Cleanup and Organization:** - Remove redundant imports and duplicated code. - Organize imports according to PEP 8 guidelines (standard library imports, third-party imports, local application/library specific imports). - Remove commented-out code that is not needed. - Delete the `del` statements at the end of functions, as they are unnecessary; Python's garbage collector will handle it. 2. **Function Decomposition:** - Break down large functions into smaller, more manageable ones. For example, `apply_mask`, `display_instances`, and `transparent_back` can be separate functions outside of `mrcnn`. - Ensure that each function has a single responsibility and is named appropriately. 3. **Performance Optimization:** - Avoid using loops for image processing when vectorized operations can be used with NumPy for better performance. - Minimize the use of `os.path.join(os.getcwd(), ...)` by setting a base directory at the start of the script and using it throughout. - Use list comprehensions and generator expressions where appropriate for better performance and readability. 4. **Code Readability:** - Add docstrings to functions to explain their purpose, parameters, and return values. - Use meaningful variable names that make the code self-explanatory. - Follow PEP 8 style guidelines for consistent code formatting. 5. **Error Handling:** - Add proper error handling and input validation to make the script robust. - Use try-except blocks where necessary to catch potential exceptions. 6. **Integration with Other Packages:** - Ensure that the script's functions and classes are easily importable and usable by other scripts in the package. - If the script shares common functionality with other scripts, consider creating a shared utility module. 7. **Testing:** - Write unit tests for the functions to ensure they work as expected and to facilitate future refactoring. - Use continuous integration tools to run tests automatically. 8. **Remove Global Variables:** - Avoid using global variables. Instead, pass necessary data as parameters to functions. 9. **Resource Management:** - Use context managers (`with` statement) for managing resources like files to ensure they are properly closed after use. 10. **Comments and Documentation:** - Update comments to reflect changes in the code. - Provide a module-level docstring explaining the purpose of the script and how to use it. 11. **Version Control:** - Commit changes incrementally with clear, descriptive commit messages. - Consider using feature branches if working in a team. By applying these refactoring steps, the `voiture_origine.py` script will be cleaner, more maintainable, and better integrated within the CCTV-Inundation-Detection package.

Changes on packages/utils.py

To refactor the `utils.py` script, we can follow these steps to improve code quality, optimize performance, and ensure it integrates well with the rest of the package: 1. **Code Organization and Comments**: Ensure that the code is well-organized with functions logically grouped together. Add or update comments to clarify the purpose of each function and important blocks of code. 2. **Use of Constants**: Replace magic numbers and strings with named constants. This makes the code more readable and easier to maintain. 3. **Error Handling**: Improve error handling by using more specific exceptions and providing helpful error messages. 4. **Function Refactoring**: Break down long functions into smaller, more manageable ones. This improves readability and testability. 5. **Type Annotations**: Add type annotations to function signatures to clarify the expected types of arguments and return values. 6. **Performance Optimization**: - Use list comprehensions where appropriate for more concise and faster code. - Consider using `os.scandir()` instead of `os.listdir()` for potentially better performance when dealing with a large number of files. 7. **Code Duplication**: Identify and eliminate any duplicated code. For example, the `process_train_info` and `process_val_info` functions are very similar and could be combined into a single function with a parameter to control whether to apply data augmentation. 8. **Testing**: Add unit tests for each function to ensure they work as expected and to facilitate future refactoring. 9. **Integration**: Ensure that the refactored code integrates well with other scripts in the package. This may involve updating function calls and imports in other scripts. 10. **Documentation**: Update or add docstrings to each function to explain what it does, its parameters, and its return value. 11. **Configuration File**: Consider using a configuration file or environment variables for settings that might change, such as the `val_rate` or supported file extensions. 12. **Use of Global Variables**: Avoid the use of global variables within functions. If a global variable is necessary, ensure it is declared as such. 13. **Plotting Function**: The plotting code within `read_split_data` could be extracted into a separate function for better modularity. 14. **File Handling**: Ensure that files are properly closed after use. For example, use the `with` statement when opening files to ensure they are automatically closed. 15. **Code Style**: Follow PEP 8 style guidelines for Python code to improve readability and consistency. Here's an example of how you might refactor the `read_split_data` function with some of the above suggestions: ```python import os import json import random from typing import Tuple, List # Constants SUPPORTED_EXTENSIONS = [".jpg", ".JPG", ".jpeg", ".JPEG"] CLASS_INDICES_FILE = 'class_indices.json' def read_split_data(root: str, val_rate: float = 0.2) -> Tuple[List[str], List[int], List[str], List[int]]: """ Reads and splits the data into training and validation sets. Parameters: - root: The root directory of the dataset. - val_rate: The proportion of data to be used for validation. Returns: - A tuple containing lists of image paths and labels for training and validation. """ random.seed(0) assert os.path.exists(root), f"dataset root: {root} does not exist." flower_class = [cla for cla in os.listdir(root) if os.path.isdir(os.path.join(root, cla))] flower_class.sort() class_indices = {k: v for v, k in enumerate(flower_class)} with open(CLASS_INDICES_FILE, 'w') as json_file: json.dump(class_indices, json_file, indent=4) train_images_path, train_images_label, val_images_path, val_images_label = [], [], [], [] every_class_num = [] for cla in flower_class: images = [os.path.join(root, cla, i) for i in os.listdir(os.path.join(root, cla)) if os.path.splitext(i)[-1] in SUPPORTED_EXTENSIONS] image_class = class_indices[cla] every_class_num.append(len(images)) val_path = random.sample(images, k=int(len(images) * val_rate)) for img_path in images: if img_path in val_path: val_images_path.append(img_path) val_images_label.append(image_class) else: train_images_path.append(img_path) train_images_label.append(image_class) print(f"{sum(every_class_num)} images were found in the dataset.\n" f"{len(train_images_path)} for training, {len(val_images_path)} for validation") return train_images_path, train_images_label, val_images_path, val_images_label ``` This refactoring includes type annotations, use of constants, and improved error handling. Similar refactoring can be applied to other parts of the script.
