New Bilateral Error Concealment Method of Entire Depth Frame Loss for 3DTV and Virtual 3D Videoconferencing Systems

In three-dimensional television and 3D videoconferencing systems, depth entire frame loss will degrade the video quality. In this paper, a bilateral error concealment algorithm of the depth entire frame loss is proposed, which utilizes strong temporal correlation and movement correlations between the depth video and its corresponding 2D color video. Experimental results show that the proposed algorithm can conceal the lost entire depth frame and provide better subjective and objective quality of the reconstructed images.
