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. Platform: |

Description: canny edge detector，下面是canny edge detector的算法： 1.将图像与高斯函数做卷积，获得平滑图像。 2.用基于平滑梯度方向的方法确定图像局部边缘的法向。 3.根据局部边缘的法线方向求解边缘位置。 4.计算边缘强度，并对梯度幅值进行非极大值抑制。 5.用双阈值算法检测和连接边缘。该文件提供了canny edge detector的VC实现代码。-canny edge detector, the following is a canny edge detector algorithm: 1. will make the image with the Gaussian convolution function to obtain a smooth image. 2. Gradient-based smoothing method to determine the direction of the edge of the image of local law to. 3. According to the local normal direction to solve the edge of the edge location. 4. Calculation of the edge strength, gradient amplitude and non-maxima suppression. 5. To use dual-threshold algorithm for edge detection and connection. The document provides a canny edge detector realize the VC code. Platform: |

Description: java语言实现的具有应用程序界面的canny算法实现，代码编写的可读程度高，并有本人的详细注释。现在网上只有canny算法的java代码，并没有应用程序界面的canny算法实现，所以很多代码不知道能不能用，也不知道效果如何。本程序全面解析了canny算法的java实现，并且达到了很好的效果。canny算法是非常重要的单像素边缘提取算法，对他的理解可以使你明白很多的图像处理手段。-java language application program interface with the canny algorithm, a high degree of code written in readable, and my detailed notes. Now online only canny algorithm java code, not the application interface canny algorithm, so a lot of code does not know can not use, do not know how it works. The program' s comprehensive analysis of the canny algorithm java implementation, and achieve good results. canny algorithm is very important single-pixel edge detection algorithm, for his understanding can make you understand a lot of image processing tools.
