Medical image Compression using Dwt Technique and its Optimization

Abstract

Image  compression  is  a  significant technology  in  the storage and transmission  of  digital  images since massive data  is incorporated in all the related applications. As nowadays the entire globe is moving on the road to filmless imaging, Medical image compression has become one of the uncompromising requisite. One of the common and extensive technique used for Image compression is discrete wavelet transform (DWT). In this technique, the input signal is transformed into elementary frequency components. This paper depicts an optimized form of DWT implemented with MatLab programming and the efficiency is measured in terms PSNR, MSE, Entropy and SSIM
