背景差视频运动目标检测算法存在的鬼影问题对智能视频监控应用有着严重的影响。通过实验发现鬼影和真实目标的前景差分图像具有不同的边缘相似特性,根据这一特性,定义图像边缘相似性度量函数,提出一种基于边缘相似性的鬼影判别方法。实验结果表明,与传统方法相比,该方法具有速度更快、适应性更好等优点。
The problem of ghost objects seriously affects the intelligent video surveillance application in background subtraction method for moving objects detection in videos.According to the characteristic that the ghost's foreground and the true object's foreground are different in the similarities of edge,and by defining edge similarity measure functions,this paper presents a ghost discriminant algorithm based on edge similarity.Experimental results show that compared with traditional methods,this method is effective and robust.
