说明：  在粒子滤波+颜色直方图+遮挡处理的基础上，加上颜色模板的更新，使程序能够适应目标颜色变化（模板直方图更新速度根据目标颜色变化的快慢手动调节）。
(In the particle filter+ Color histogram+ Block deal on the basis of the updated template to add color, so that procedures can be adapted to the target color changes (template update speed histogram color changes depending on the target speed manual adjustment).)
