All Medical pix incorporate some visible and unvisible random disturbances. These are termed as noises. It represents undesirable statistics that deteriorates the image quality. There are different types of noises in photographs and it can be efficaciously eliminated through the usage of filters. So in widespread filters are used to decrease the noise with the aid of smoothing and additionally used to beautify the edges. Filters are usually been labeled as linear and non linear filters. Linear filters are incapable of smoothing besides concurrently blurring the edges. In our context we are going to enforce a median 2 filter, Wiener filter, imadjsut filter, both tophat and bothat filters(morphology) for filtering 2D X-ray images. These combination of filters yields the best part in the preprocessing techniques. It gives a good PSNR and MSE values.
