Wavelet transform affords wide space for image coding algorithms because of its excellent space-frequency localization characterizations. The compact supported  symmetrical and biorthogonal wavelet has linear phase  so it is applied on image compression area widely. The lifting scheme is an efficient method for constructing the wavelet filter after multiresolution. Under the condition of biorthogonal  biorthogonal wavelet base can be constructed freely according to the wavelet performance. And it can quicken the implementation speed of the wavelet transform. Analyzing the algorithm of lifting scheme is applying for constructing biorthogonal wavelet. Experimental results indicate that the method of the biorthogonal wavelet that has good performances with SPIHT is applying for image compression  so as image synthesis performs well. 2005 IEEE.   Flow Instability and Its Control in Compression Systems 期刊论文  OAI收割 JOURNAL OF THERMAL SCIENCE, 2003, 卷号: 12, 期号: 1, 页码: 1,9 Jingyi Chen 收藏  |  浏览/下载：17/0  |  提交时间：2013/03/11 compressors  rotating stall  pre-stall  active/passive control  wavelet.
