canny算法源码。Canny 的目标是找到一个最优的边缘检测算法。Canny 算法适用于不同的场合。它的参数允许根据不同实现的特定要求进行调整以识别不同的边缘特性。对于PC上的实时图像处理来说可能慢得无法使用，尤其是在使用大的高斯滤波器的情况下。但也要考虑到处理器速度的不断提升。 -canny algorithm source code. Canny' s goal is to find an optimal edge detection algorithm. Canny algorithm is applied to different occasions. It allows the parameters to achieve specific requirements according to different adjustments in order to identify characteristics of different edge. For real-time image processing on a PC is probably too slow can not be used, especially in the use of a large Gaussian filter circumstances. But we should also take into account the processor speed has been increasing.
