基于改进的canny算子边沿提取算法，比八连同区域的的方法更精确。

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

自己编的canny改进算法，里面有详细的注释附带检测的图片。对于目标分割用处很大。-Own series of canny improved algorithm, which has detailed notes with pictures of detection. Proved very useful for object segmentation.
