Design and Simulation of Matlab/Simulink Model for Edge Detection Techniques in Image Segmentation

Rakesh M.R

Edge detection is the important part of image processing. Edge detection is one of the processes to detect the sharp changes in intensity value (pixel value) of the image. There are many edge detection techniques are there. The commonly used are Sobel, Robert, Prewitt, Canny’s edge detection technique. Canny’s technique is more optimal compared to other techniques. In this paper we deal with MATLAB/SIMULINK model for Sobel, Robert, Prewitt and Canny’s edge detection technique and the corresponding simulation results. So Canny’s technique is gives best result in presence of noise. The edge detection technique used in feature detection and feature extraction from an image.
