差分帧法的目标跟踪的主要思想是，将当前帧图像与前一帧图像做一个差分，对差分的图像取绝对值后进行二值化-The main idea is to target track of the difference frame method, the image of the current frame and a previous frame image to make a difference, taking the absolute value of the differential image af

这是基于亮色互补的牌照二值化方法，内容详细，方法简单，值得参考！-This is based on light-colored license complementary binarization method, detailed method is simple, it is also useful!

这个工程实现了通过迭代阈值法将图像二值化。-The project achieved through the iterative threshold method to image binarization.
