MaixPy image class missing most useful functions #470

Closed marcusobrien closed 2 years ago

marcusobrien commented 2 years ago

Describe the bug Maix Py image class is missing many useful image processing functions like find_lines()

Dir the image class and it only has these functions

import image dir(image) ['class', 'name', 'ASCII', 'Image', 'ImageReader', 'ImageWriter', 'UTF8', 'font_free', 'font_load', 'get_affine_transform', 'grayscale_to_rgb', 'lab_to_rgb', 'rgb_to_grayscale', 'rgb_to_lab', 'warp_affine_ai']

The API docs mention functions like findlines for example **"The line object is returned by image.find_lines, image.find_line_segments or image.get_regression.

10.1. Constructor# class image.line

Please call image.find_lines(), image.find_line_segments(), or image.getregression() function to create this object.**"

Using kflash_gui I installed the latest maix firmware on a Maix Bit device

maixpy_v0.6.2_83_gf0280db50_minimum_with_ide_support.bin

And when I run the code I get python error AttributeError: 'Image' object has no attribute 'find_lines'

To Reproduce Steps to reproduce the behavior:

  1. Go to the example code on this page [(https://wiki.sipeed.com/soft/maixpy/en/api_reference/machine_vision/image/image.html)]

  2. Copy and paste into IDE with Maix Bit

  3. Click connect Link Icon

  4. Run program with Big green play button the code

  5. AttributeError: 'Image' object has no attribute 'find_blobs'

  6. The image class has lots of missing functions mentioned in the API docs

image Python module - missing functions are mage.find_lines, image.find_line_segments and image.get_regression.

Expected behavior The image class should support what is in the API docs mage.find_lines, image.find_line_segments or image.get_regression.

Actual behaviour These functions are not supported mage.find_lines, image.find_line_segments and image.get_regression.

Thanks @Neutree - Great - this worked. I didnt think I this "non-minimum" binary package would work with the IDE, as I thought only binaries named "with_ide_support" could be used with the IDE. But this "normal/full package" does include the additional code and classes, as well as work with the IDE.
