Description: Canny认为一个优良的边缘检测算子应具有以下3个特性:
① 好的检测性能。不漏检真实边缘，也不把非边缘点作为边缘点检出，使输出的信噪比最大。
② 好的定位性能。检测到的边缘点与实际边缘点位置最近。
③ 唯一性。对于单个边缘点仅有一个响应。-Canny think a good edge detector should have the following three characteristics: ① good detection performance. Not missed a true edge, nor the non-edge points as edge points detected, so that the maximum output signal to noise ratio. ② good positioning performance. Detected edge point and the actual location of the edge recently. ③ unique. For a single edge point only one response.

Description: 由于噪声点(灰度与周围点相差很大的点)对边沿检测有一定的影响，所以效果更好的边沿检测器是高斯拉普拉斯(LOG)算子。它把我们在第3章中介绍的高斯平滑滤波器和拉普拉斯锐化滤波器结合了起来，先平滑掉噪声，再进行边沿检测，所以效果会更好。-As the noise points (points, a big difference with the surrounding gray points) on the edge detection to a certain extent, the effects are therefore a better edge detector is the Laplace Gaussian (LOG) operator. It is our described in Chapter 3 of the Gaussian smoothing filter and Laplacian sharpening filter combines first smooth out the noise, and then to edge detection, it would be more effective.

Description: canny检测器是很有效的边缘检测器，该函数可以实现对目标图像的边缘提取。该方法总结如下：1.图像使用带有指定标准差的高斯滤波器来平滑，以此减少噪声；2.在每一点计算局部梯度和边缘方向；3.第二步中确定的边缘点会导致梯度幅度图像中出现脊，然后追踪所有脊的顶部，并将所有不再脊顶部的像素设置为0；4.执行边缘链接-canny detector is very effective edge detector, this function can be achieved on the target image edge detection. This method is summarized as follows: 1. Image used with the specified standard deviation of the Gaussian filter to smooth out, thereby reducing the noise 2. In the calculation of each point of local gradient and edge direction 3. The second step in determining the edge points will led to the image gradient magnitude ridge appears, and then keep track of all of the top of the ridge, and ridge at the top of all the pixels are no longer set to 0 4. the implementation of the edge link
