基于对称差分的背景减法运动目标检测

提出了一种基于对称差分和背景差分相结合的运动目标检测方法。先通过多帧图像平均法取得初始背景图像,并结合采集到的当前帧图像和前一时刻的背景获得更新背景,采用背景减法获取前景目标;同时运用对称帧差法取得前景图像,用两种差分图像进行或运算,提取到运动目标,用形态学方法进行后期处理。实验结果表明,该方法能够有效地获取运动目标。

A moving target detection algorithm based on symmetric difference and background subtraction

A motion detection method based on symmetric difference and background difference is presented in this paper. First of all, the initial background image is obtained through a multi-frame averaging method, the background is updated with the current frame image and the prior background , and the background subtraction method is used to acquire the foreground object. With the symmetrical frame difference, another foreground image can be obtained at the same time. Then the OR operation is done with two differential images to extract moving target, and post-processing is completed by using morphological method. Experimental results show that the method can get moving target effectively.
