摘要:This paper deals with performance evaluation of well known image compression algorithm i.e. wavelet based image com-pression Set Partition in hierarchical Tree (SPIHT) and decomposition algorithm known as Singular Value Decomposition (SVD). Due to multi resolution nature of wavelet transforms, SPIHT provides better image compression at higher compression ratio. The techniques are implemented in MATLAB and compared using the performance parameters PSNR, MSE, CR and compressed size. Images obtained with SPIHT technique yields higher compression ratio and better visual quality
