In this paper a combination of an initial disparity estimation using the line-wise hybrid recursive matcher and a subsequent post-processing and up-sampling step using variations of cross-bilateral filtering is presented. The proposed algorithm is realtime capable for image resolutions up to HD and scales well with large disparity ranges. It is specifically designed to allow for a high degree of parallelization and for temporally consistent disparity maps for use in video processing. In terms of quality the proposed method can compete with most recent real-time or near-real-time capable disparity estimators.
