Coarse-to-Fine PatchMatch for Dense Correspondence.

Although the matching technique has been studied in various areas of computer vision for decades, efficient dense correspondence remains an open problem. In this paper, we present a simple but powerful matching method that works in a coarse-to-fine scheme for optical flow and stereo matching. Inspired by the nearest neighbor field (NNF) algorithms, our approach, called coarse-to-fine PatchMatch, b...
