Digital image processing includes many factors like Image enhancement, segmentation, object recognition, removal of noise and many more. Noise removal is the one of the hot area of image processing. Noise can be minimized but cannot removed completely. Scientist and researchers has established many filters, which can minimize the noise in the image and enhance its quality. There are many types of noise and many types of filter for the removal of noise. Many types of noise are used. To remove these types of noise, 3 x 3 average filter is used in this paper and its efficiency is measured. The simulations are performed on the MATLAB.
