Cost volume filtering based stereo matching with improved matching cost and seco

Recent cost-volume filtering-based local stereo methods have.achieved comparable accuracy with global methods. However,.there are still some significant outliers existing in the.final disparity map. In this paper, we propose a cost-volume.filtering-based local stereo matching method that employs a.new combined cost and a novel secondary disparity refinement.mechanism. The combined cost is formulated by a modified.color census transform, truncated absolute differences.of color and gradients. Symm
