Let's consider an image of a natural scene ;we 've got some individuals (pixels) that may differ one from another (different colors).(adsbygoogle = window.adsbygoogle || []).push({});

the entropy E of the system is E=sigma(-p.logp), where the sum is computed over the colors and p is the probability of occurence of a given color.

the issue here is that E simply does not depend on the location of the pixels within the image and thus does not depend on the "shapes" or "object" that one can perceive in the image (tress, etc): E only depends on the histogram of the pixels but not on the geometry of the image...

can anyone suggest a way to estimate the complexity of images of the world?
