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. WebNov 29, 2012 · Edge detection is the approach used most frequently for segmenting images based on abrupt (local) changes in intensity.
