The set of chromatophores were drawn on 29 images of size 1544x1038 pixels from 9 different acquisition sequences. The 29 images were cut into pieces of 256x256 pixels for the creation of the model giving 696 thumbnails. On all the images, this corresponds to 25919 chromatophores classified as "light" and 26819 chromatophores classified as "dark".
The programs to build the model and use it as well as our current model are available on this gitlab.
