| Abstract: | A method for image compression of biorthogonal wavelet transform based on lifting scheme with SPI- HT(Set Partitioning In Hierachical Trees)is proposed.The lifting scheme is an efficient method for construct- ing 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 SPI- HT is applying for image compression.so as image synthesis performs well. |
| Keywords: | wavelet transform biorthogonal lifting scheme image compression SPIHT |
