Abstract


This article defines research about edge detection systems with their functions, pros and cons. For this purpose we will compare existing edge detection procedures lying under the 3 categories a) 1st order derivative/gradient methods (sobel, prewitt's, robert's operator) b) 2nd order derivatives / zerocrossing (laplacian of gaussian, difference of gaussian) and c) optimal methods (canny operator). Comparison is finished on the foundation of side detected pictures with their PSNR (peak signal to noise ration) and MSE (mean square error) values for exclusive strategies.
