چکیده

An efficient algorithm addressing robust disparity estimation based on region information is proposed. In the proposed method, a new adaptive-size window approach is introduced to stereo matching in order to overcome problems with fixed-size window. The reliability of disparity estimation is then measured with a criterion based on uniqueness and smoothness constrains. In occluded areas and image points with unreliable disparity assignments, region-based interpolation strategy is applied to compensate the disparity values. Experimental results with natural stereo pairs show that the proposed algorithm provides good disparity map and can be used for synthesizing intermediate views with high quality. Key-Words: Disparity estimation, region information, adaptive-size window, reliability measurement, region-based interpolation
