ELECTRONICS AND COMMUNICATIONS IN JAPAN PART I-COMMUNICATIONS 2000年 第11期83卷 66-75页
作者: Osawa, H Suzuki, K Kato, S Yasuda, Y Canon Inc CX Project Kawasaki Kanagawa 2118501 Japan Utsunomiya Univ Fac Engn Utsunomiya Tochigi 3210912 Japan Waseda Univ Grad Sch Sci & Engn Tokyo 1690072 Japan
Image coding is discussed in two phases;one is transformation of image signals using a coding model, and the other is entropy coding which assigns a code to a transformed sequence. A well-known example of the latter i... 详细信息

ELECTRONICS LETTERS 2002年 第4期38卷 170-172页
作者: Yoo, H Joeng, J Hanyang Univ Dept Elect Commun Engn Seoul 133791 South Korea
A signal-dependent wavelet transform based on the lifting scheme is proposed. The transform can be made reversible (i.e. an integer-to-integer transform). The reversible transform. followed by arithmetic coding, is ap... 详细信息
