Abstract : Edge is known to be an important changes of intensity in a digital image. It is a sudden changes of discontinuous noticed in an image. The three types of edges are: Horizontal, Vertical and digital images. In this paper, different edge detection methods are reviewed and comparing of different edge detection method, with their advantages and disadvantages. Implementation was done using MATLAB.

Keywords : Edge Detection, Prewitt Operator, Sobel Operator, Log Operator, Canny Operator.
