Decoder-driven mode decision in a block-based distributed video codec
收藏 引用
MULTIMEDIA TOOLS AND APPLICATIONS 2012年 第1期58卷 239-266页
作者: Mys, Stefaan Slowack, Juergen Skorupa, Jozef Deligiannis, Nikos Lambert, Peter Munteanu, Adrian Van de Walle, Rik Ghent Univ IBBT Multimedia Lab Dept Elect & Informat Syst ELIS Gaston Crommenlaan 8 Bus 201 B-9050 Ghent Belgium Vrije Univ Brussel IBBT Elect & Informat Dept ETRO B-1050 Brussels Belgium
distributed video coding (DVC) is a video coding paradigm in which the computational complexity is shifted from the encoder to the decoder. DVC is based on information theoretic results suggesting that, under ideal co... 详细信息

An Error Resilient video coding Scheme Using Embedded Wyner-Ziv Description with Decoder Side Non-Stationary Distortion Modeling
收藏 引用
IEEE TRANSACTIONS ON CIRCUITS AND SYSTEMS FOR video TECHNOLOGY 2011年 第4期21卷 498-512页
作者: Zhang, Yongsheng Xiong, Hongkai He, Zhihai Yu, Songyu Chen, Chang Wen Shanghai Jiao Tong Univ Dept Elect Engn Shanghai 200240 Peoples R China Univ Missouri Dept Elect & Comp Engn Columbia MO 65211 USA SUNY Buffalo Dept Comp Sci & Engn Buffalo NY 14260 USA
In this paper, we propose a generic error resilient video coding (ERVC) scheme using embedded Wyner-Ziv (WZ) description. At the encoder side, a joint source-channel R-D optimized mode selection (JSC-RDO-MS) algorithm... 详细信息
