Patent ID: 8571349

Claim:
A computer-implemented method of enhancing an image, comprising: receiving an original image; automatically defining, by a processor, a set of sites for the original image, each site being a candidate to be patched and having a first resolution; receiving one or more images related to the original image; and for a first site of the set of sites, performing operations comprising: identifying a plurality of candidate labels from the one or more related images, each candidate label being a pixel region of one of the related images that is a potential patch for the first site and that has a second resolution higher than the first resolution; producing down-sampled label data by converting a label of the candidate labels from the second resolution to the first resolution; performing a pixel-by-pixel comparison of pixels in the down-sampled label data with corresponding pixels of the first site; determining a degree of difference between the label and the first site based on the pixel-by-pixel comparison; automatically selecting the label as a patch for the first site, the label selected responsive at least in part to the degree of difference between the label and the first site; and enhancing the image by applying the patch to the first site.
