Image enhancement is a technique used in the areas of multimedia, medical imaging and other numerous applications. As the quality of image is very much dependent on light, weather or equipment that we used to capture the picture. We propose to employ wavelet transform, curvelet transform and wave atom for denoising of medical images having gaussian noise The main purpose of image enhancement in medical imaging is to provide better results. To solve the problem of reinstating an image from noisy image we have done some comparative analysis. Experimental results show the denoising method by wavelet transform is less effective than the other methods because both curvelets and wave atoms have very high degree of directional specificity. We have used some registered sets of Medical Images like MRI, Ultrasound and quality parameters like MSE, PSNR to know the quality of images
