Fuzzy Logic Technique Based Image Contrast Enhancement

Image enhancement plays a vital role in image processing technique. This paper presents a Novel method for image enhancement by using Fuzzy. In this proposed algorithm, the RGB image converted into HSI (Hue, Saturation and Intensity) model, where as Intensity and Hue color considered for Image enhancement after conversion. The Hue component decomposed into directional co-efficient by Fuzzy. The higher directional coefficients are eliminated as it causes artifact and unnatural efforts in a image and the intensity components of image is contrast enhanced by using Fuzzy. The performance of the proposed image enhancement method is compared with existing histogram equalization and contrast limited adaptive histogram equalization based image enhancement. The result of the proposed method achieves satisfactory performance in visualization.
