摘要
提出一种改进的运动目标检测算法,首先将视频序列中的一整幅画面进行分割,对分割产生的每块图像进行连续检测,一旦检测到有变化,即提取运动目标。接着将连续2帧差图像和背景差图像直接相乘,再将相乘的结果进行二值化处理得到运动检测结果,从而将运动目标从背景图像中分离出来,最终得到视频序列图像中运动存在与否的一个二值运动模板,由此提高运动目标检测的效果。
An improved algorithm for moving target detection is introduced. First, one image is segmented into several units, and then each of them is detected sequent. Once there is a change, the moving target can be got. Second, the result image of two successive frames and background are directly multiplied and the result is binary operated to get the moving result. Consequently, the moving target can be separated from the background image. Finally, a binaries motion template which included the motive information of the target is got, and the effect of moving target detection can be improved.
