How to determine the texture of the image?

Question

So we have such a photo

_{(source: vkontakte.ru )}

How to find out that a white figure is painted on a red wall, and that this white figure is a texture, and how to cut this wall out of the picture? I need an algorithm to perform such an operation programmatically (not manually)

Answer 1

Given that this is a difficult task for a person, I expect that at present this cannot be done algorithmically. It is difficult to compete with a visual processing system that has been more than 200 million years in the specification refinement stage with coding errors punishable by death.

If you are doing research in this area, a good place to start would be Vese and Osher's “Modeling Textures with Total Minimization of Variations and Oscillating Patterns in Image Processing” (see Vese Publications Page ). In particular, Figures 14 and 15 show the results of applying their method to a similar image (albeit with more detailed details).
