Modified SPIHT Algorithm Based on Ladder Property of Subband Extreme Value
Xiaofeng Chen · Jisuanji gongcheng · 2005
Set Partitioning in Hierarchical Tree(sSPIHT)algorithm exploits the spatial self-similarity between subband in same spatial orientation,but not in same level. It achieves efficient result and applies in image coding based on wavelet. This paper exploits the ladder property betweensubband extreme value and modify SPIHT algorithm. Both theoretic analysis and experiment results confirm good compression performance andlow complexity at the same time.
