Smoothing algorithms for clip-and-paste model-based video coding
收藏 引用
IEEE TRANSACTIONS ON CONSUMER ELECTRONICS 1999年 第2期45卷 427-435页
作者: Hao, SS Lee, MF Yang, JF Natl Cheng Kung Univ Dept Elect Engn Tainan 701 Taiwan
model-based video coding has been adopted as a core experiment in ISO MPEG-4 standard. The clip-and-paste technique for putting video objects in line is an important tool to reduce the transmission rate. To assist the... 详细信息

A robust model generation technique for model-based video coding
收藏 引用
IEEE TRANSACTIONS ON CIRCUITS AND SYSTEMS FOR VIDEO TECHNOLOGY 2001年 第11期11卷 1188-1192页
作者: Siu, M Chan, YH Siu, WC Hong Kong Polytech Univ Dept Elect & Informat Engn Ctr Multimedia Signal Proc Hong Kong Hong Kong Peoples R China
In conventional model-based coding schemes, predefined static models are generally used. These models cannot adapt to new situations, and hence, they have to be very specific and cannot be generated from a single gene... 详细信息
