First- and Second-Order Full-Differential in Edge Analysis of Images by Dong-Mei Pu, Yu-Bo Yuan

“…Experiments on Corel5K and PASCAL VOC 2007 are done to show the difference between the first order and the second order. After comparison with Canny operator and the proposed first-order differential, the main result is that the second-order differential has the better performance in analysis of changes of the context of images with good selection of control parameter.…”
