本程序是基于帧差的运动目标检测，速度快，可符合实时检测的要求，并给出了运动方向。-The procedure is based on frame difference of moving target detection, fast, able to meet the requirements of real-time detection and gives the direction of motion.

运动模糊，基于空域的方向检测，包括经典的那几篇文献-Motion blur detection, based on the direction of the airspace that several documents including the classic

模糊角度和模糊长度是运动模糊的两个主要参数，代码简单介绍这两个参数的提取。-Motion direction and motion length are the two important parameters of motion blur.The code simply introduces the detection of the parameters.
