ABSTRACT
Image de-noising is the technique to reduce noises from corrupted images. The aim of the image denoisingis to improve the contrast of the image or perception of information in images for human viewersor to provide better output for other automated image processing techniques. This paper presents a newapproach for color image de-noising with Fuzzy Filtering techniques using centroid method fordefuzzification. It preserves any type of edges (including tiny edges) in any direction. The experimentalresult shows the effectiveness of the proposed method.
