Abstract
Determining correspondence between image regions can include: selecting first and second regions of visual content including pixels in a computer system, the first region comprising a first patch to be mapped to the second region; selecting at least two heuristics for use in mapping the first patch to the second region, the heuristics selected from the group consisting of: (i) nearby-pixel mapping evaluation; (ii) random-perturbation mapping evaluation; (iii) evaluation of multiple mapping candidates identified in an iterative search process; and (iv) enrichment to increase a collection of mapping candidates; and identifying, using the selected heuristics, at least one patch in the second region for the first patch.
