CamShift 是一种应用颜色信息的跟踪算法，在跟踪过程中，CamShift 利用目标的颜色直方图模型得到每帧图像的颜色投影图，并根据上一帧跟踪的结果自适应调整搜索窗口的位置和大小，从而得到当前图像中目标的尺寸和中心位置。(CamShift is a color-based tracking algorithm. In the process of object tracking, CamShift operates on a back-projectionimage produced fromobject histogrammodel. Computed information is used previously to adjust current search window size and location,then the location and size of the color object are found.)
