# Photo mosaic

This openFrameworks application generates [photo mosaics](https://en.wikipedia.org/wiki/Photographic_mosaic). Specify a target image ("outer image") and a directory of candidate images and the program will assign all the candidate images to a tile in the mosaic. All candidates are assigned exactly once with none missing and no duplicates. Thus the following [samples](https://www.flickr.com/photos/genekogan/albums/72157666460255840) are all made of exactly the same tiles, which is the animals categories of the [Caltech-256](http://www.vision.caltech.edu/Image_Datasets/Caltech256/images/) dataset. Samples:

### How it works

1) the target image is divided into a matrix of tiles, and a color histogram is extracted from each of the target image's tiles, as well as all the candidate images from the specified directory.

2) a distance measurement is extracted between every possible pair of tile and candidate image. the metric used is the [Earth Mover's Distance](https://en.wikipedia.org/wiki/Earth_mover%27s_distance) (EMD) between the histograms of each tile and candidate.

3) the candidates are assigned to the grid so as to minimize the total EMD.
