EDGE-PRESERVING DISPARITY ESTIMATION AND DISPARITY-COMPENSATED INTERMEDIATE VIEW

摘要

A constrained disparity estimation method is proposed which uses a directional regularization technique to efficiently preserve edges for stereo image coding. The pro- posed method smoothes disparity vectors in smooth regions and preserves edges in object boundaries well, without creating an oversmoothing problem. The differential pulse code modulation (DPCM) technique for disparity map coding is used prior to entropy coding, in order to improve the overall coding efficiency.
