Hi A friend of mine want's to manipulate pictures (bitmap, in color). Basically, he want's to load and then represent them as a binary vector in Sage and then encode them using linear codes -> manipulations (errors) -> then back to an image and see how good the code worked. The one thing I don't know is what's the best and easiest way to get a binary representation of an image to be able to work with - a bijection from picture to binary vector in GF(2) and back. Maybe in different versions (each color channel separate or other methods).
