Abstract:
1. A method, comprising: determining initial matching patches at image grid locations of a first digital image and a second digital image; determining a motion field for each matching patch based on motion data of neighboring matching patches effective to enforce spatial coherency of each matching patch in the second digital image with reference to respective matching patches in the first digital image; initiating a multi-resolution iterative process to update each spatially coherent matching patch based on overlapping grid regions of the matching patches that are evaluated for larger matching regions of the first and second digital images down to smaller matching regions of the first and second digital images; and determining an optimal, spatially coherent matching patch at each of the image grid locations based on minimizing a local cost function that includes a data term and a spatial coherent term, the data term comprising a patch distance between matching patches at an image grid location of the first and second digital images, and the spatial coherent term comprising a summation of a coherency of matching patches based on a distance of motion vectors between neighboring matching patches.
