摘要: 为了改进目前常用的运动目标检测方法易受到噪声和亮度突变的影响、易出现虚假目标的情况,该文提出了一种基于3帧差分和边缘信息的运动目标检测方法。该方法首先对连续3帧图像进行边缘提取得到3帧连续的边缘图像,然后对3帧连续的边缘图像进行3帧差分运算,最后通过阈值分割和形态学处理完成对目标的提取。该方法计算简单,实验结果表明该方法能对运动目标进行准确检测,且具有很好的鲁棒性。

Abstract: A moving object detection algorithm based on three-frame-differencing and edge information is presented in this paper. Firstly, three continuous edge images are obtained by edge extract from three continuous images, and then, the motion information is detected with three-frame-differencing, finally, the object is extracted with threshold segmentation and morphology. The result shows that the detection algorithm can detect object accurately and quickly. -
