A method has been devised for performing edge operations with various edge operators under varying imaging conditions and for quantitatively comparing the results of each edge operator. Both computer-simulated targets and real targets are employed, and experiments in both cases showed that the Sobel operator and Kirsch Compass Gradient Mask are better than the Highpass and Laplacian filters in the performance of edge operation.
