Abstract:
When transmitted over error-prone environments, the stereoscopic video data may undergo transmission errors and loss. In order to improve the quality of the reconstructed video, a Joint Multi-view Coding (JMVC) based error concealment method for stereoscopic video is proposed in this paper. In this method, the errors in the independent view are concealed by traditional two-dimensional (2-D) video error concealment algorithm. For the lost macroblock (MB) in the dependent view, intra and inter-view correlation are utilized to conceal the errors based on the characteristics and its coding mode of the stereoscopic videos. Combined with related reference MBs’ partition mode, the lost MBs are divided into two types: smooth block and texture block. Smooth block is to be processed by improved Boundary Smooth Degree (BSD), while reconstruction of texture block is done by unit of 8×8 block with related pixel Sum of the Absolute Differences (SAD). Experimental results show that, compared with
the conventional error concealment methods for stereoscopic video coding, the proposed method can achieve better subjective and objective performances.
