Abstract
Official abstract text for this publication.
In embodiments of spatially coherent nearest neighbor fields, initial matching patches of a nearest neighbor field can be determined at image grid locations of a first digital image and a second digital image. Spatial coherency can be enforced for each matching patch in the second digital image with reference to respective matching patches in the first digital image based on motion data of neighboring matching patches. A multi-resolution iterative process can then update each spatially coherent matching patch based on overlapping grid regions of the matching patches that are evaluated for matching regions of the first and second digital images. An optimal, spatially coherent matching patch can be selected for each of the image grid locations of the first and second digital images based on iterative interaction to enforce the spatial coherency of each matching patch and the multi-resolution iterative process to update each spatially coherent matching patch.
First claim
Opening claim text (preview).
The invention claimed is: 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…
