A New Modified Fuzzy Rule Based Edge Detection
Main Article Content
Abstract
Edge is a basic feature of image. The image edges include rich information that is very significant for obtaining the image characteristic by object recognition.Edge detection is the most commonly used technique in image processing. So this paper represents a modified rule based fuzzy logic technique, because fuzzy logic is desirable to convert the uncertainties that exist in many aspects of image processing. Here firstly the gradient and standard deviation is calculated and used as input for fuzzy system. This is applied on traditional algorithm like Sobel, Prewitt , LoG and then the results are compared with modified algorithm and concluded that the proposed technique is to find the more fine edges and reduce the pixels that are not belonging to the edge.
