- 利用当前帧图像与背景图像对应象素点的灰度差值来检测车辆。如果当前图像的象素点和背景图像的象素点灰度值差别很大，就认为此象素点有车通过；相反，如果当前图像的象素点和背景图像的象素点灰度值差别较小，在一定的阈值范围内，我们就认为此象素点为背景象素点。-Using the current frame image and the background image corresponding to the difference between the pixel gray vehicle is detec

- 三帧差分算法是相邻两帧差分算法的一种改进方法，它选取连续三帧视频图像进行差分运算，消除由于运动而显露背景影响，从而提取精确的运动目标轮廓信息。该算法的基本原理是是先选取视频图像序列中连续三帧图像 并分别计算相邻两帧的差分图像，然后将差分图像通过选取适当的阈值进行二值化处理，得到二值化图像，最后在每一个像素点得到的二值图像进行逻辑与运算，获取共同部分，从而获得运动目标的轮廓信息。-Three differential algorithm is an improved method of two

Background-difference-method
- 背景差分法是采用图像序列中的当前帧和背景参考模型比较来检测运动物体的一种方法,其性能依赖于所使用的背景建模技术。背景差分法检测运动目标速度快，检测准确，易于实现，其关键是背景图像的获取。在实际应用中，静止背景是不易直接获得的，同时，由于背景图像的动态变化，需要通过视频序列的帧间信息来估计和恢复背景，即背景重建，所以要选择性的更新背景。-Background difference method is the use of images in the sequence of the current
