摘　　要：为从视频图像序列中准确且完整地提取运动目标,提出一种基于运动差分直方图的目标提取算法。通过对视频图像序列中两帧相邻图像以及它们的差分图像进行逐次分块,分析对应分块的差分直方图,利用背景区域块与目标区域块对应的差分直方图分布不同,逐步去除背景提取目标,有效避免提取的目标内部出现空洞,以块为单位的处理提高算法运行速度。通过数值实验验证了该算法具有较好检测性。To accurately and completely extract moving target from the video image sequence,a moving target detection algorithm based on the movement difference histogram was proposed.The successive block for two adjacent images of video image sequence algorithm and their difference image were used,the difference histogram of corresponding blocking was analyzed,the background region and the different distribution of corresponding difference histogram of target area block were used to gradually remove the background to extract the target,which effectively avoided the hole within the target,and taking block as the unit of processing improved the algorithm of computing speed.Finally,the better detection of the proposed algorithm is demonstrated by the numerical experiments.
