车牌识别程序，使用sobel算子检测边缘，然后准确定位车牌，准确率高达98％以上。-license plate identification procedures, the use of pixel edge detection operator, and then accurate positioning plates, accuracy rate was as high as 98% or more.

这是自己写的车牌定位代码 初定位采用的是水平投影的方法 细定位采用的是小波变换的方法 -This is his license plate positioned to write the code first uses the horizontal projection of the positioning method is used in fine positioning of the wavelet transform method
