1. A computer-implemented method for determining correspondence between image regions, the method comprising:

  • selecting, by a computer system, first and second regions of visual content that includes pixels, the first region comprising a first patch to be mapped to the second region;

    performing iterations to find mappings for the first patch, the iterations including nearby-pixel mapping evaluation and random-perturbation mapping evaluation, at least one of the nearby-pixel mapping evaluation or the random-perturbation mapping evaluation performed on a different number of candidate patches than second patches found in the second region in at least one of the iterations; and

    recording the second patches in the second region found using the iterations.
