Paper Abstract

For wireless multi-view video system, whose abilities of storage and computation are all very weak, it is essential to have an encoder device with low-power consumption and low-complexity. In this paper, a DCT-domain Wyner-Ziv residual coding scheme with low encoding complexity is proposed for wireless multi-view video coding (WZRC-WMS). The scheme is designed to encode the residual frames of each view independently without any motion or disparity estimation at the encoder, so as to shift the large computational complexity to the decoder. At the decoder, the proposed scheme performs joint decoding with side information interpolated from current view and adjacent views. Experimental results show that the proposed WZRC-WMS scheme outperforms the H.263+ interframe coding about 1.9dB in rate-distortion performance, while the encoding complexity is only 1/17 of that of H.264 interframe coding.
