Toward fast Wyner-Ziv video decoding on multicore processors
收藏 引用
MULTIMEDIA TOOLS AND APPLICATIONS 2014年 第3期68卷 717-745页
作者: Corrales-Garcia, Alberto Luis Martinez, Jose Fernandez-Escribano, Gerardo Quiles, Francisco J. Univ Castilla La Mancha Inst Invest Informat Albacete Albacete 02071 Spain
The Wyner-Ziv video coding paradigm provides a framework where most of the complexity is moved from the encoder to the decoder. In this way, Wyner-Ziv coding efficiently supports multimedia services for mobile devices... 详细信息
