摘要：

Image processing is one of the major aspects of signal processing. Like any other signal, images can also be hampered by noise. Filters need to be designed and implemented, to remove these unwanted signals. There could be various types of noise affecting the images and, accordingly, different types of filters need to be designed. In this paper, median type of filter is designed for different kinds of noise. Also, a study of this filter is made to determine which type of noise they are suitable for. The mean square error determines whether the designed filter is suitable for the given image and the noise or not. The estimated image is the noise filtered out from the given image. Processing is done using the MATLAB software and the image has been processed by MATLAB codes.
