A jointly optimized subband coder
The mainstream approach to subband coding has been to partition the input signal into subband signals and to code those signals separately with optimal or near-optimal quantizers and entropy coders. A more effective approach, however, is one where the ...
Low-complexity and low-memory entropy coder for image compression
A low-complexity and low-memory entropy coder (LLEC) is proposed for image compression. The two key elements in the LLEC are zerotree coding and Golomb-Rice (1966, 1991) codes. Zerotree coding exploits the zerotree structure of transformed coefficients ...
A perceptually tuned embedded zerotree image coder
ICIP '97: Proceedings of the 1997 International Conference on Image Processing (ICIP '97) 3-Volume Set-Volume 1 - Volume 1Embedded zerotree wavelet coding (EZW), introduced by Shapiro (1993) and improved by Said and Pearlman (1996) using an algorithm based on set partitioning in hierarchical trees (SPIHT), is a computationally inexpensive image coding technique and has ...
