车牌检测与识别技术的相关技术： 提出一种梯度增强法对图像边缘进行增强, 该方法主要通过对图像本身信息进行简单梯度变换以突出图像边缘, 并辅以数学形态学中的膨胀法实现牌照的快速定位. 在字符分割部分, 给出了最小面积旋转法以确定牌照的最佳旋转角, 并采用垂直投影法分割牌照中的字符 -License plate detection and recognition technology related technologies: a gradient-enhanced

用于矩形检测的源代码，已配说明，易看懂。但不适合于车牌检测等复杂的矩形检测-Rectangular detection for the source code has been assigned that easy to understand. But not suitable for detection of license plate detection rectangular complex

基于二值化和边缘检测的车辆牌照自动定位的系统-Binarization and edge-based detection of vehicle license plate positioning system

这是图像处理中的车牌检测，是用matlab编写实现的。-This is the license plate detection, image processing is achieved using matlab.
