This paper presents a study on edge marking scheme of various standard edge detectors viz.Sobel, Prewitt, Roberts, Laplacian of Gaussian (LoG) and Canny.On the basis of edge map obtained for a synthetic rectangular board image, obtained from five edge detectors, suggests classifying the detectors in three categories namely, pre-marker, post-marker and mixed-marker.Pratt's figure of merit (PFOM) is used as a quantitative evaluation criterion for the above mentioned classification.Experimental results obtained for Lena and Parrot image provides convincing results to establish proposed classification.
