The aim of clustimage
is to detect natural groups or clusters of images. It works using a multi-step proces of carefully pre-processing the images, extracting the features, and evaluating the optimal number of clusters across the feature space.
The optimal number of clusters can be determined using well known methods suchs as silhouette, dbindex, and derivatives in combination with clustering methods, such as agglomerative, kmeans, dbscan and hdbscan.
With clustimage
we aim to determine the most robust clustering by efficiently searching across the parameter and evaluation the clusters.
Besides clustering of images, the clustimage
model can also be used to find the most similar images for a new unseen sample.
A schematic overview is as following:
clustimage
overcomes the following challenges:
* 1. Robustly groups similar images.
* 2. Returns the unique images.
* 3. Finds higly similar images for a given input image.
clustimage
is fun because:
* It does not require a learning proces.
* It can group any set of images.
* It can return only the unique() images.
* it can find highly similar images given an input image.
* It provided many plots to improve understanding of the feature-space and sample-sample relationships
* It is build on core statistics, such as PCA, HOG and many more, and therefore it does not has a dependency block.
* It works out of the box.

On the documentation pages you can find detailed information about the working of the clustimage
with many examples.
conda create -n env_clustimage python=3.8
conda activate env_clustimage
pip install clustimage # new install
pip install -U clustimage # update to latest version
pip install git+https://github.com/erdogant/clustimage
from clustimage import clustimage
The results obtained from the clustimgage library is a dictionary containing the following keys:
* img : image vector of the preprocessed images
* feat : Features extracted for the images
* xycoord : X and Y coordinates from the embedding
* pathnames : Absolute path location to the image file
* filenames : File names of the image file
* labels : Cluster labels
In this example we will be using a flattened grayscale image array loaded from sklearn. The unique detected clusters are the following:
