In distributed video coding (DVC), efficient compression is achieved by exploiting source statistics at the decoder only, which is radically different from conventional video coding. The pixel-domain Wyner-Ziv video coding is a kind of typical distributed video coding scheme, in which the encoder can be very simple and the complexity of the coder is transferred to the decoder. The performance of pixel-domain Wyner-Ziv video codec is greatly dependent on quality of side information and reconstruction arithmetic. In this paper we propose an improved method of pixel-domain Wyner-Ziv video coding based on side information estimate and decoding reconstruction at the decoder. The results of simulation tests show that better visual quality and average 1.5dB gain can be achieved by applying the proposed method.
This paper proposes a novel multi-stage frame error concealment (EC) algorithm for H.264/AVC based on estimated MB modes and MVs. The proposed method first divides the lost frame into three regions according to MB fea...
