Hybrid Wyner-Ziv coders which employ a combination of Wyner-Ziv coding and differential pulse code modulation (DPCM) encoding have recently gained popularity for applications such as video coding. In this paper we analyze the low-rate operational rate distortion performance of Wyner-Ziv coding using uniform scalar quantization, in the context of such hybrid coders. Motivated by video we consider the...
Wyner-Ziv (WZ) coding has recently been proposed as a low encoding complexity alternative to traditional DPCM coding for compression of sources with memory, in particular, in applications like multimedia compression. The viability of this alternative approach clearly depends on the compression performance of WZ coding compared to that of DPCM coding. In an attempt to understand the performance gap...
Wyner-Ziv coding has recently emerged as an alternative to conventional DPCM coding for compression of sources with memory, particularly in video compression. This paper studies the operational rate-distortion performance of Wyner-Ziv coding, using uniform scalar quantization followed by perfect Slepian-Wolf coding, for compression of a Laplace-Markov source. The performance gap of this technique...
