3D Video communication scheme for error prone environments based on motion vector sharing

Abstract

The Emergence of three dimensional (3D) video applications, based on Depth Image Based Rendering (DIBR) has brought about new dimensions to the video transmission problem, due to the need to transmit additional depth information to the receiver. Until the transmission problem of 3D video is adequately addressed, consumer applications based on 3D video will not gain much popularity. Exploiting the unique correlations that exist between the color and their corresponding depth images, will lead to more error resilient video encoding schemes for 3D video. In this paper we present an error resilient 3D video communication scheme that exploits the correlation of motion vectors in color and depth video streams. The presented method achieves up to 0.8 dB gain for color sequences and up to 0.7 dB gain for depth sequences over error prone communication channels.
