Edge detection is the most important pre-processing step in image processing. In this paper we studied various edge detection methods and different kinds of operators using edge detection. The various edge detection techniques such as Robert, sobel, prewitt, canny are compared with each other. In end a new nature inspired algorithm has been proposed and compared with the traditional operators. We...
In order to get an enhanced image and for extracting useful information, an image is first converted into digital form and after that various operations are performed on it. Image edge detection is one of the most important preprocessing step in image processing. In this paper, we compare various traditional edge detection methods such as Canny, Prewitt, Robert and Sobel. Also we propose edge detection...
