Each of the datasets has about 2.7 bits of entropy per colour channel per pixel (they're 8-bit colour values) - surprisingly, there's not much variation between the datasets, although that's probably because my algorithm is blind to the actual structure of the image. I'm trying to figure out how to use Matlab so I can play with some more advanced tests.
