Then a vertical edge matching based algorithm recognizes license-plate from input gray-scale image.

然后根据这种算法进行垂直边界匹配来从输入的灰度图像中识别车牌。

The other method uses 1-D cyclostyle matching algorithm to obtain horizontal and erect gray scale projection curves of two list images, then compares with them if its not homology.

另一种方法是分别得到横竖条码在水平和垂直方向的一维灰度投影曲线，根据它们的相关性判断两幅图像是否匹配。
