在传统canny边缘检测的基础上，进一步进行自适应阈值的边缘检测方法的研究，比传统的方法有很大的优越性-Traditional canny edge detection on the basis of further adaptive threshold edge detection method, there are a lot of advantages than traditional methods

有关改良Canny算法的一些还算可以的文献-Improved Canny algorithm on some literature.

Article explaining Canny algorithm

Edge detection algorithms are important tools in image processing applications for carrying out much information and being relatively easy to produce. Sobel Canny and logarithmic algorithms [1] are among several edge detection algorithms used
