Sjaandi CircleCI Coverage Status PyPI Python License

Use your images to create collages based on visual similarity, where similar images are located close to each other, like in the example below:

Example

Note: This work was inspired by Andrej Karpathy's visualizations of ImageNet dataset.

1. Installation

Sjaandi is available for installation using pip:

pip install sjaandi

2. Using the Library

All you need is to have all images for collage in one folder, and use that path as input to VisualSearchEngine():

from sjaandi import VisualSearchEngine

DATA_PATH = # path to the folder with images

collage = VisualSearchEngine(DATA_PATH).make_collage()

The collage will be a square, two-dimensional grid of square images. If the number of pictures in your folder is not a square of some number, some photos will not end up in the collage. For example, if you provide 50 images, you will get a 7-by-7 collage having 49 images, which means 1 of the pictures of the 50 will not be included.

3. Technical Details

Underneath the hood, this library puts your images through a neural network and collects high dimensional activations. The activations are mapped to a two-dimensional Cartesional space using the t-SNE algorithm. The next step is to transform the t-SNE coordinates into a square lattice of coordinates. Finally, your images are laid out at lattice coordinates to produce the final image.
