Shaifali Pande, Vivek Singh Bhadouria, Dibyendu Ghoshal . A Study on Edge Marking Scheme of Various Standard Edge Detectors. International Journal of Computer Applications. 44, 9 ( April 2012), 33-37. DOI=10.5120/6294-8491
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.
