A Novel H.264 Based Motion Vector Recovery Method for 3D Video Transmission

摘要

The performance of 3D video transmission over error-prone channels is limited by the channel noise. Error concealment is an effective method to combat these channel errors. In H.264 video coding, motion vectors (MVs) are highly significant for the matching of the missing video block. Thus how to recover the lost MV is an important issue for error concealment in 3D video communications. In this paper, we propose a new method to recover the corrupted MVs for 3D video transmission, which is based on the traditional boundary matching algorithm (BMA) for the 2D video. Our proposed depth based BMA (DBMA) method will make full use of the relationships between the 2D video and depth map to recover the lost MV based on BMA. Experimental results show that it is highly effective and significantly outperforms other existing MV recovery methods for 3D video error concealment at different block loss ratios (BLRs)1.
