canny边缘检测,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。但是，我们讨论计算能力的时候，也要考虑到随着处理器速度不断提升，有望在未来几年使得这不再成为一个问题。-canny edge detection, Canny algorithm is suitable for different occasions. It allows the parameters adjusted according to the specific requirements of different implementations to identify different edge characteristics. For real-time image processing on a PC, it may not be too slow to use, especially when using large Gaussian filter case. However, we discuss the computational power of the time, also taking into account rising as processor speed, is expected to make in the next few years, this is no longer a problem.
