Abstract
A method of compensating for match errors while generating a super-resolution image, includes receiving, at a processor, an input image having a first resolution forming a low resolution layer, identifying a patch in a unknown high resolution image layer, identifying a corresponding low resolution patch in the low resolution layer, finding at least one matched patch in a match layer having a resolution lower than the first resolution, identifying at least one copy patch in a copy layer having a resolution lower than the high resolution layer, the copy patch to be copied to the high resolution layer, determining an match error between the at least one matched patch and a corresponding low resolution patch, selecting a matrix to transform the match error to provide compensation for the high resolution patch as match error compensation, and modifying the high resolution patch using the match error compensation.
