The impact of tree structures on the performance of zerotree-based wavelet video codecs
收藏 引用
SIGNAL PROCESSING-image COMMUNICATION 2010年 第3期25卷 179-195页
作者: Moinuddin, Athar Ali Khan, Ekram Ghanbari, Mohammed Aligarh Muslim Univ Dept Elect Engn Aligarh 202002 UP India Univ Essex Sch Comp Sci & Elect Engn Colchester CO4 3SQ Essex England
In this paper we analyze the impact of tree structures on the performance of zerotree-based wavelet video codecs. Since zerotree approach is based on aggregation of insignificant coefficients in trees, therefore desig... 详细信息

DISPLAYS 2015年 40卷 68-77页
作者: Kim, Sunwoong Lee, Donghyeon Kim, Hyun Truong, Nguyen Xuan Kim, Jin-Sung Seoul Natl Univ Dept Elect & Comp Engn Seoul 151744 South Korea Sun Moon Univ Dept Elect Engn Asan 336708 South Korea
In general, to achieve high compression efficiency, a 2D image or a 2D block is used as the compression unit. However, 2D compression requires a large memory size and long latency when input data are received in a ras... 详细信息
