Type2 Fuzzy Soft Computing Technique for Image Enhancement

Abstract

<p class="Default">The mainpurpose of Image enhancement is to process an image so that outcome is more appropriate than original image for definite application. The fuzzy logic isone of the soft computing techniques to enhance the images by eliminating uncertainty.In this paper efficient type2 fuzzy logic technique is used to get betterquality image. This method consists of two steps. In the First step fisher criterion function is useful to generate type1 fuzzy membership value. In the second step based on type1 membership value fuzzy rules are derived to enhance the image. The type2 fuzzy method is compared with type1 fuzzy. The table values and graphs provethat the proposed method gives better results compared with fuzzy type1 method.</p>

A Review on Image Enhancement Techniques

“…The detailed description of type-II fuzzy set can be found in [14]. Survey paper like [15] presenting a detailed overview of image enhancement using fuzzy techniques. The main advantage of those techniques is to enhance the contrast and improve the quality of the image.…”

“…A lot of authors are proposing various medical image enhancement techniques using type-II fuzzy approach. The [15] proposes type-II fuzzy computing techniques for image enhancement. The [16] proposes Edge detection method based on type-II fuzzy system for color images.…”
