Look into SIFT features (patented, so be careful about commercial use) and other gradient histogram based keypoint descriptors. You don't actually need machine learning for this, a SIFT extractor and some sort of nearest neighbour lookup data structure will do. You might use PCA or something to reduce the dimensionality of the nearest neighbour problem, though.
