- 介绍一种实用的二维条码识别算法。首先探讨了二维条码的定位与分割算法,利用Hough变换与Sobel边缘检测把条码图像从原始采集的图像中有效地分割出来 然后分析了条码图像经过光学系统的噪声模型,提出了一种计算点扩展函数标准方差的算法 采用Flourier变换自适应地选取阈值去除噪声导致的无效边界,从而得到条码的基本模块。实验结果表明,该算法具有很好的抗噪性,提高了二维条码的识别率。 -A practical two-dimensional barcode recognition algorit

license-plate-recognition
- 本程序采用一种基于垂直Sobel算子检测边缘和投影法的车牌定位方法,根据车牌区域竖直纹理突出的特点,利用Sobel垂直算子提取边缘,然后投影得到车牌的水平投影图,利用水平投影图分割出车牌,再运用膨胀运算进行车牌垂直定位。利用旋转投影法寻找车牌倾斜角度,然后用双线性插值进行车牌图像倾斜矫正。对经过精定位的车牌利用垂直投影法,找出各个字符的中心点,根据字符中心点位置进行切割。同时将切割出来的图片与数据库中的每张模板图片进行减法运算,计算该图片与模板的均方误差,其均方误差最小的模板即为识别出的字符。-
