Recent research in transform based compression techniques has concentrated on wavelet transform due to its superior performance. Compression in transform domain is possible either in the quantization stage or bit allocation stage. In this paper, an approach to compress the image by integrating the human visual system model into the quantization stage of the wavelet transform is presented. Evaluations are performed on medical images and the performance is analysed quantitatively using mean square error and peak signal to noise ratio.Keywords
