摘要 根据车牌图象的灰度特性选用一种线性,自适应算法对车牌图象进行增强处理,旨在去噪声,消模糊,同时保持良好的边缘.实验结果表明,增强后的二值化图象质量有明显的改进,说明这种算法是行之有效的. In order to inhibit the noise ,decrease the effect of blurring and protect the edge of thetargetimage ,in this paper ,we enhance the car - nu m ber images using a kind of nonlinear ,adaptivefilter according to the characteristic of its gray - scale . Experiments show that the quality of bina rized image enhanced by this method is has been significantly im proved ,and it proves that thismethod is practical and useful .
