摘要
当视频监控的背景较复杂或目标动态性强时易出现目标检测不完整的问题,通过定义两种误检情况下的评价函数动态调整阈值R,提出了一种阈值自适应更新的改进ViBe算法,并针对交通监控视频容易出现的阴影问题提出一种融合颜色特征和角点特征的阴影消除方法。实验结果表明,改进ViBe算法可以有效地解决传统ViBe算法在复杂情况下运动目标检测不完整的问题,且阴影消除效果良好,可以被广泛应用在视频监控领域。
When the background of video surveillance is complex or the target is strongly dynamic,the problemof incomplete target detection is easy to appear.By defining the two evaluation functions in two misdiagnosis to dynamically adjust the threshold R!an improved ViBe algorithm with adaptive threshold updating is proposed.And a shadow elimination met!iod based on color featiure and corner feature is proposed for the shadow problemwhich is easy to appear in the traffic surveillance video.The experimental re-sults show that the improved ViBe algorithmcan effectively solve the problemof incomplete detection of moving targets in the com-plex situation of traditional ViBe algorithm,and the effect of shadow elimination is good,so it can be widely used in the field of video surveillance.
