An Image is often corrupted by noise in its acquisition ortransmission. Nose is any undesired information that contaminates an image. Noise appears in images from variety of sources. The purpose of denoising is to remove the noise while retaining as much as possible the important signal features. De noising can be done through Filtering techniques. In this Paper the performance of Average and Median filters is analyzed based on their ability to remove noise. Here Impulse noise is added to both gray scale and color images And then both Averaging and Median Filtering techniques are applied to the noisy images using MATLAB. The experimental results are shown which indicate the better filtering technique for the purpose of salt and pepper noise removal in the digital images.
