An Image Sharpening Method by Suppressing the Noise

Abstract

Image Processing refers to the use of algorithm to perform processing on digital image. Microscopic images like some microorganism images contain different type of noises which reduce the quality of the images. Removing noise is a difficult task. Noise removal is an issue of image processing. Images containing noise degrade the quality of the images. Removing noise is an important processing task. After removing noise from the images, the visual effect will not be proper. Image Sharpening in an image is basically a process of extracting high frequency details from the image and then adding this information to the blurred image. This paper presents an approach to a de-noise method for noisy image and a method of sharpening of the noisy image.
