A New Edge Detection Method based on Max and Min Values of the Pixels

Edge is defined as boundary between two different intensities of the image pixels which means difference in intensity of the pixel in the image. The edges for the image are always the important features that introduce an indication for a higher frequency. There are many methods of programs in mat lab to perform edge detection. The most common method for edge detection is to calculate the differentiation of an image called Prewitt edge. This paper proposes a method to detect an edge of image depending on the maximum and minimum of the pixel values that requires less computation time than Prewitt and Sobel Operators.
