An improved application of probabilistic relaxation to edge labeling is presented. WebSecond-order approaches to edge detection. Some edge-detection operators are instead based upon second-order derivatives of the intensity. This essentially captures the rate of change in the intensity gradient. Thus, in the ideal continuous case, detection of zero-crossings in the second derivative captures local maxima in the gradient. csusb mph
