| 摘 要： | 提出了一种对实摄图像的变形矫正算法。它通过对目标区域在水平和垂直方向计算差分，并对投影所得结果计算方差，找出使方差达到最大的直线，并按这两条直线来对原图进行矫正。结果显示，用此方法不仅对于矫正实摄车辆牌照字符的变形有较好的效果，而且对其他字符以及一些图形图象也有一定的矫正效果。

| Abstract: | An deformation remedy algor ithm for real image is proposed. The algorithm c omputes the horizontal and vertical difference of target region, then project the difference image to two line bunch, computes variance and finds the lines which make the variance achieve maximum. The two lines can be used to remedy the orig in image. Experiments show that this algorithm can be used not only in the deformation of license plat e character, but also in other character and some im ages and graphics. |
