REMOVING SALT AND PEPPER NOISE FROM THE IMAGE BY THE USE OF THRESHOLD MECHANISM

Abstract

Image processing is the mechanism which is required in case of almost every image since distortion is present within the image. Image restoration and removing noise will be the prime objective of the proposed paper. Number of methods has been proposed each having their own advantages and disadvantages. A novel approach to handle salt and pepper noise is suggested in this paper. In the proposed scheme two pass mechanisms is suggested. In the first phase the image is passed from the median filter and improved image is received. The improved image is then passed through the proposed technique known as threshold paradigm. Within the threshold mechanism the values of the maximum co-ordinates associated with the image will be stored. The pixel values exceeding the threshold will be rejected and improved image will be obtained.
