英文摘要	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. Symmetric guided filter is used for the cost aggregation. Different from traditional stereo matching, a novel secondary disparity refinement is proposed to further remove remaining outliers. Experimental results on Middlebury benchmark show that our method ranks the 5th out of the 144 submitted methods, and is the best cost-volume filtering-based local method. Furthermore, experiments on real world sequences also validate the effectiveness of our proposed method.; EI; CPCI-S(ISTP); jianbojiao@sz.pku.edu.cn; rgwang@pkusz.edu.cn; wangwenmin@pkusz.edu.cn; dongsf@pkusz.edu.cn; wangzhenyu@pkusz.edu.cn; wgao@pku.edu.cn; Septmber; 2014-September
