Description: 讨论和比较了几种常用的边缘检测算子。梯度
算子计算简单 ,但精度不高 ,只能检测出图象大致的轮廓 ,而对于比较细的边缘可能会忽略。Prewitt 和Sobel算子比 Roberts 效果要好一些。LOG 滤波器和 Canny算子的检测效果优于梯度算子 ,能够检测出图象较细的边缘部分。不同的系统 ,针对不同的环境条件和要求 ,选择合适的算子来对图象进行边缘检测。-Discussion and comparison of several commonly used edge detection operator. Gradient operator is simple, but accuracy is not high, only to detect the outline of the image generally, and for the more detailed the edge may be ignored. Prewitt and Sobel operator is better than Roberts effect. LOG filter and Canny operator detection better than gradient operator, can detect the edge of a smaller part of the image. Different systems for different environmental conditions and requirements, choose a suitable operator to image edge detection.

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

Description: SIFT 由特征提取，特征描述符描述和特征匹配 3 部分构成，该算子特征提取数目庞大，建立特征描述符运算
量高，导致算法效率低。提出了一种 SEC( SIFT-Edge-Corner) 算法，在图像尺度空间提取角点代替 SIFT 特征点，并根
据角点是边缘曲率极值理论，预先采用 Canny 算子得到高斯边缘图像金字塔，再提取角点并进行尺度选择。实验结
果表明: 该算法在保障高准确率的前提下大幅度提高特征提取效率-By the SIFT feature extraction, feature descriptions and feature matching descriptors 3 parts, the large number of feature extraction operator established feature descriptor computation high, resulting in low efficiency of the algorithm. Presents a SEC (SIFT-Edge-Corner) algorithm, the image scale space instead of SIFT feature extraction corner points and corner points based on extreme value theory is an edge curvature in advance using Canny operator edge image obtained Gaussian pyramid, and then extract corner point and scale selection. Experimental results show that: the algorithm protect high accuracy under the premise of feature extraction efficiency greatly improved

Description: 首先，针对车牌图像预处理采用了灰度化、中值滤波等的算法。其次，车牌定位的模块中研究了基于Canny的车牌边缘检测算法和形态学操作，提高了系统定位的准确率。然后，用基于垂直投影的垂直切分算法对车牌进行字符切分。最后采用模板匹配的算法对车牌字符进行识别。 -Firstly, the license plate is with a gray image preprocessing, median filtering algorithm. Secondly, the plate positioning module and morphological study of the detection algorithm are based on license plate edge Canny operator, which improve the positioning accuracy of the system. Then, the license plate character is segmented which is based on the vertical projection of the vertical segmentation algorithm. Finally, I can use the template matching algorithm to recongnize the license plate character.
