MEDICAL IMAGE DENOISING BASED ON GAUSSIAN FILTER AND DWT SWT BASED ENHANCEMENT TECHNIQUE

Image pre-processing techniques are used to improve the quality of an image before processing into an appliance. These will improve visual quality of image for image interpretation. This paper proposes a pre-processing technique for noise removal and enhancement based on Gaussian filter and DWT, SWT based image interpolation method which gives better results compared to state-of-art criteria like DWT based enhancement technique.
