Camshift它是MeanShift算法的改进，称为连续自适应的MeanShift算法，CamShift算法的全称是 Continuously Adaptive Mean-SHIFT ，它的基本思想是视频图像的所有帧作MeanShift运算，并将上一帧的结果（即Search Window的中心和大小）作为下一帧MeanShift算法的Search Window的初始值，如此迭代下去。-CAMSHIFT it is improved meanshift algorithm, called for continuous adaptive meanshift algorithm and CAMSHIFT algorithm s full name is　continuously adaptive Mean-SHIFT . Its basic idea is all the frames of video image meanshift arithmetic and the result of a frame (i.e. search window center and size) as the next frame meanshift algorithm search window of the initial value, so the iteration continues.
