PatchMatch: A Randomized Correspondence Algorithm for Structural Image EditingPatchMatch: A Randomized Correspondence Algorithm for Structural Image Editing Structural image editing. Left to right: (a) the original image; (b) a hole is marked (magenta) and we use line constraints (red/green/blue) to improve the continuity of the roofline; (c) the hole is filled in; (d) user-supplied line constraints for retargeting; (e) retargeting using constraints eliminates two columns a
