摘要:This paper deals with performance evaluation of well known image compression algorithm i.e. wavelet based image compression Set Partition in hierarchical Tree (SPIHT) and DCSPIHT. DCSPIHT algorithm is the hybrid combination of DCT and SPIHT coding. Due to multi resolution nature of wavelet transforms, SPIHT provides better image compression. The techniques are implemented in MATLAB and compared using the performance parameter PSNR. Images obtained with SPIHT technique yields higher signal to noise ratio.
