In the era of telemedicine a large amount of medical information is exchanged via electronic media mostly in the form of medical images, to improve the accuracy and speed of diagnosis process. Medical Image denoising has the basic importance in image analysis as these algorithm and procedures affects the efficacy of medical diagnostic. In this paper focus is on Multi wavelets based Image denoising techniques, because they provide the possibility of designing wavelets systems which are orthogonal, symmetric and compactly supported, simultaneously. Performance of Discrete Multi Wavelet Transform and Discrete Wavelet Transform based denoising methods are compared on the basis of PSNR.
