clustimage 1.7.1

Python package clustimage is for unsupervised clustering of images.

clustimage

clustimage is a Python library to detect natural groups or clusters of images. Multiple steps are pipelined where images are processed, features extracted, and the clusters evaluated across the feature space. The optimal number of clusters is determined using methods such as *silhouette, dbindex, and derivatives* in combination with clustering methods, such as *agglomerative, kmeans, dbscan and hdbscan*. clustimage allows you to determine the most robust clustering by efficiently searching across the parameters and by evaluating the clusters. Besides clustering of images, the ``clustimage`` library can also find the most similar images for a new, unseen sample. ⭐️Star it if you like it⭐️

clustimage overcomes the following challenges:

* 1. Robustly groups similar images.
* 2. Returns the unique images.
* 3. Finds highly similar images for a given input image.
* 4. Cluster on datetime or latlon coordinates when using photos.

clustimage is fun because:

* It does not require a learning process.
* 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 can map photos on an interactive map with thumbnails and cluster labels so that you can easily structure your photos.
* It provided many plots to improve the  understanding of the feature-space and sample-sample relationships
* It is built on core statistics, such as PCA, HOG, EXIF data, and many more, and therefore it does not have a dependency block.
* It works out of the box.

Installation

It is advisable to create a new environment (e.g. with Conda).

conda create -n env_clustimage python=3.8
conda activate env_clustimage

Install bnlearn from PyPI

pip install clustimage            # new install
pip install -U clustimage         # update to latest version

Directly install from GitHub source

pip install git+https://github.com/erdogant/clustimage

Import clustimage package

from clustimage import clustimage

Examples

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

Examples Mnist dataset:

Example: Clustering mnist dataset

In this example we will be using a flattened grayscale image array loaded from sklearn. The unique detected clusters are the following:

Click on the underneath scatterplot to zoom-in and see ALL the images in the scatterplot

Example: Plot the explained variance

Example: Plot the unique images

Example: Plot the dendrogram

Examples Flower dataset:

Example: cluster the flower dataset

Example: Make scatterplot with clusterlabels

Example: Plot the unique images per cluster

Example: Plot the images in a particular cluster

Example: Make prediction for unseen input image
