Description: 车牌识别系统
使用说明
使用时打开此例题目录下pic中的图片，然后依次单击按钮“转”、“1”、“2”、“3”、“4”和“5”，就可以实现精确的车牌定位。
具体步骤
1.24位真彩色->256色灰度图。
2.预处理:中值滤波。
3.二值化:用一个初始阈值T对图像A进行二值化得到二值化图像B。
初始阈值T的确定方法是:选择阈值T=Gmax-(Gmax-Gmin)/3,Gmax和Gmin分别是最高、最低灰度值。
该阈值对不同牌照有一定的适应性,能够保证背景基本被置为0,以突出牌照区域。
4.削弱背景干扰。对图像B做简单的相邻像素灰度值相减,得到新的图像G,即Gi,j=|Pi,j-Pi,j-1|i=0,1,…,439 j=0,1,…,639Gi,0=Pi,0,左边缘直接赋值,不会影响整体效果。
5.用自定义模板进行中值滤波
区域灰度基本被赋值为0。考虑到文字是由许多短竖线组成,而背景噪声有一大部分是孤立噪声,用模板(1,1,1,1,1)T对G进行中值滤波,能够得到除掉了大部分干扰的图像C。
6.牌照搜索:利用水平投影法检测车牌水平位置,利用垂直投影法检测车牌垂直位置。
7.区域裁剪,截取车牌图像。-number plate recognition system for use when used to break pic examples directory of images, Click the button followed by a "U-turn", "1", "2" and "3" and "4" and "5", can achieve precise positioning of the plates. Concrete steps 1.24 true color-

Description: 检测车牌VC++程序。用自定义模板进行中值滤波
区域灰度基本被赋值为0。考虑到文字是由许多短竖线组成,而背景噪声有一大部分是孤立噪声,用模板(1,1,1,1,1)T对G进行中值滤波,能够得到除掉了大部分干扰的图像C。-License plate detection VC++ Procedures. Custom template gray-scale median filter basic region was assigned to 0.

Description: 文章提出了一种车牌照字符倾斜的校正方法, 该方法基于Hough 变换和Radon 变换。用Hough 变换检测车牌照上下两边,并对水平倾斜的牌照进行水平校正, 再用Radon 变换检测字符垂直倾斜角度并进行垂直校正, 实验结果表明车牌图像经过二次校正大大减少了字符切分的困难, 有利于后面字符的正确识别。-This paper presents a vehicle license plate characters tilt correction method based on Hough transform and Radon transform. Hough transform to detect vehicle license plate with the top and bottom, and the license to the level of horizontal tilt correction, then the character Radon transform to detect vertical tilt and vertical adjustment, the experimental results show that the correct license plate image is greatly reduced secondary character segmentation difficulties, is conducive to correctly identify the characters behind.
