Robust stereo matching with fast normalized cross-correlation over shape-adaptive regions KU Leuven
Normalized Cross-Correlation (NCC) is a common matching technique to tolerate radiometric differences between stereo images. However, traditional rectangle-based NCC tends to blur the depth discontinuities. This paper proposes an efficient stereo algorithm with NCC over shape-adaptive matching regions, producing depthdiscontinuity preserving disparity maps while remaining the advantage of robustness to radiometric differences. To alleviate the ...
