本文首先就传统的边缘检测算子（即一阶算子 Roberts 算子、Sobel 算子、Prewit

算子、二阶算子 Kirsch 算子、Robinson 算子和 LOG 算子）和新兴的边缘检测算子（即 Canny 算子和小波边缘检测方法）的思想和性质进行了理论和探讨，同时给

出了这些边缘检测算子的实验结果，提出了其中的不足。-In this paper, the conventional edge detection operator (that is, the first-order operator Roberts operator, Sobel operator, Prewit operator, second-order operator Kirsch operator, Robinson and LOG Operator operator) and the new edge detection operator [4] (the Canny operator and the wavelet edge detection method) and the nature of the idea and explore the theoretical and at the same time give the edge detection operator of the experimental results, one of the deficiencies raised.
