Quantitative analysis of a moment-based edge operator
Paul H. Eichel, Edward J. Delp · IEEE Transactions on Systems Man and Cybernetics · 1990
An operator that is based on the sample variance of a group of pixels is introduced. It exhibits three unique properties: freedom from a predefined shape, low computational complexity and a rigorous stochastic formulation. The utility of the latter property in applying detection-theoretic principles to the task of edge detection and in theoretical predictions of experimental performance measures is demonstrated. The operator is compared with other common edge operators on natural scenes.>
