摘要：Image compression is a fast paced and dynamically changing fi eld with many di fferent varieties of compression methods available. Wavelet transform techniques currently provide a promising approach to image compression and concentrate on achieving higher compression ratio without sacri ficing the quality of the image. In image compression, the choice of wavelet depends on the image content. The quantitative measures Compression Ratio(CR), Bit-Per-Pixel(BPP) and perceptual quality measures Mean Square Error(MSE) and Peak Signal To Noise Ratio(PSNR) are calculated for di fferent images with di fferent wavelets and comparative study has been made.
