Xuechun Wang, Shenxiao Liu, Fang Han · 2011
In order to make the image compression algorithm have higher compression ratio and better image recovery quality, based on SPIHT algorithm analysis, an efficient image coding algorithm FSPIHT(Fast Set Partitioning In Hierarchical Trees) has been proposed. The algorithm introduces the lifting wavelet and a wavelet basis (V9/3) based on human visual system, the classification of LIS (the List of Insignificant Sets) is deleted in the new compression algorithm, the hierarchical trees in wavelet decomposition are coded equally from son generation to grandson generation. The experimental result proves that the rebuilt image of this algorithm has better visual effect and moreover improves coding speed.
