摘要：
This paper presents the performance of several wavelet basesin SPIHT coding. Two types of wavelet bases are tested for SPIHT algorithm i.e. orthogonal and biorthogonal wavelet bases. The results of using coefficients of these bases are compared on the basis of Compression Ratio and Peak Signal to Noise Ratio. The paper shows that use of biorthogonal wavelets bases is better than orthogonal wavelet bases. Out of biorthogonal wavelets, bior 4.4 shows good results in SPIHT coding.
