一种可靠的运动检测方案及应用

A Reliable Scheme for Motion Detection and Application

提出了一种简单、可靠的视频序列运动检测方案。该方案首先计算相邻两帧图像对应像素的亮度信号之间的差值,比较差值与设定阈值的大小来判决该像素运动与否。为减少噪声引起的误判,使用了中值滤波、连通区域标号等操作来消除随机噪声以及虚假的静止区域。

This paper proposes a simple, yet reliable scheme for motion detection in video sequences. First, it calculates the difference between intensities of corresponding pixels in two consecutive images. If the difference is larger than a pre-defined threshold a moving pixel is detected. In order to avoid the error decision in the presence of noise, the median filtering and connected region labeling is operated to eliminate the random noise and false stationary regions.
