Image cleaning processes are applied on images to remove the different types of noise that are equally present in the image during capturing or introduced into the image during diffusion. The salt &pepper noise is the one type of noise which is happened during transmission of the images or due to bit errors or late pixels in the image substances. The images are unclear due to object movement or camera dislocation when we capture the image. If the image is cornered convert it in the gravy scale image. Convert the image to double for better accuracy. Find the median by sorting all the values of the 3*3mask in growing order. Remove the centre pixel value with the median value. Compute the Signal to Noise ratio. De convolution function is used to filter the image. This Advanced filter is the grouping of Median and Weiner filter. When we arrange these two filters in series we get the anticipated output.
