Description: 指南针边缘检测算法是当前质量最高的边缘检测方法，比CANNY算子效果还要好。具有边缘定位准确，边连续，完整的特点。程序能够得到每一个像素的边的朝向，有利于做进一步的优化应用，例如图像分割等。具体算法过程可参考斯坦福大学麦克博士发表的论文。主要思路就是以每个像素为中心，像罗盘一样转动边，一直找到两边差异最大的朝向。最后把所有的最优朝向连起来成为边缘。
代码用VC驱动，核心部分用matlab编写-Compass edge detection algorithm is currently the highest quality of edge detection methods, than CANNY operator even better results. With edge positioning accuracy, while continuous, full features. Program can be a pixel for each side towards is beneficial for further optimization of applications, such as image segmentation and so on. Specific algorithms may make reference to Stanford University Maikeboshi the published papers. Main idea is to each pixel as the center, the same rotation as the compass edge, has been to find the greatest difference between both sides of the orientation of. Finally all the best to link into the edge towards. Code using VC-driven, the core part of the preparation with matlab Platform: |

Description: 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. Platform: |

Description: 基于Matlab平台实现目标信息提取。求未含噪声的原图像的周长需先对图像进行二值化，然后选择一种算法进行边缘检测，包含prewitt,canny,sobel等算法，再通过sum(sum())函数进行周长的计算并显示在相应的位置。为求包含特定目标的噪声污染图像的周长或面积，首先对图像进行去噪，再进行二值化，接着进行微小分割，实现边缘提取或者区域分割，进一步统计目标周长或者目标面积。-Based on Matlab platform to achieve the goal of information extraction. Perimeter need to seek not contain the original noise image binarized image, and then select an algorithm for edge detection, including prewitt, canny, sobel algorithm, the circumference of the sum (sum ()) function calculated and displayed in the appropriate location. Seeking to contain a specific target image the perimeter or area of noise pollution, the first image noise, and then binarized, followed by small split, edge detection or region segmentation, and further statistical target circumference or target area.
