用canny算子实现对图像边缘的检测，效果比较好。在经典算法上进行的改进-Canny operator image edge detection, the results were quite good. Improvements in the classical algorithm

基于蚁群算法的改进进行边缘检测，改方法可行，并且速度快，与传统算法进行比较。-Based on improved ant colony algorithm for edge detection, change the method is feasible, and fast, with traditional algorithms were compared.
