Edges characterize boundaries are the problem of fundamental importance in description of geometric surfaces. Since edge detection is in the fore front of computer vision system for detection of surfaces images as Revolution and Saddle surfaces needs to description, it is crucial to have a good under standing of geometric properties of Surfaces and edge detection algorithms. In this paper the comparative analysis of various surface-image edge detection techniques and the study of the geometric properties of Surfaces are presented. The software is developed using MATLAB 7.11. It has been shown that the Canny’s edge detection algorithm performs better than all operators (i.e. Robert, Prewitt, Sobel, Zero-cross (Laplacian) and LOG) under almost all scenarios.
