Non-rigid dense correspondence

摘要

Non-rigid dense correspondence (NRDC) for image enhancement may be performed. In one embodiment, a correspondence may be computed for each one of a plurality of regions of a source image to one of a plurality of regions of a reference image. Computing the correspondences may include searching within a search range for each of a plurality of image characteristics. One or more of the correspondences may be aggregated into matched regions. A global color transform and/or deblurring may be applied to the source image. In one embodiment, the global color transform and/or deblurring may be based on the matched regions. At least one of the search ranges may optionally be adjusted. In some embodiments, computing, aggregating, applying and/or deblurring, and adjusting may be iteratively performed.

1. A method, comprising:
computing a correspondence for each one of a plurality of patches of a source image to one of a plurality of patches of a reference image, the computing includes searching within a search range for each of a plurality of image characteristics; aggregating one or more of the correspondences into matched regions; and applying a global color transform to the source or reference image resulting in an updated image, the global color transform based on estimated differences between the source image and the reference image in the matched regions.
