Conference on Visual Communications and Image Processing 2004
作者: Hong, D van der Schaar, M Pesquet-Popescu, B Columbia Univ Dept Elect Engn New York NY 10027 USA
We propose applying an adaptive context-tree weighting (CTW) method in the H.264 video coders. We first investigate two different ways to incorporating the CTW method into an H.264 coder and compare the coding effecti... 详细信息
