The steps are as follows: First, motion area is extracted based on high-order statistics detection method and motion information of multiple frames.

其基本思想是：首先根据多帧帧差信息，基于高阶统计检测方法提取运动区域。

Motion prediction taking acceleration into account could effectively reduce the detection area and it consequently increases the tracking speed.

带加速度的运动预测则有效地减小了检测区域，提高了系统的速度。

Because it only detects this small area, this method can be considered as the foundation of real time human motion detection as well as guarantees the accuracy of detection.

因为检测的区域较小，所以这种方法既保证了检测的准确性同时也为人体实时检测奠定基础。
