摘　　要：针对室内静止摄像机条件下的视频监控系统,本文提出一种简单的、自适应的背景估计方法来实时更新背景;在HM-MD色彩空间抑制运动阴影之后,采用一种改进的区域生长法来分隔出各个运动对象,并求出各目标形心位置。实验结果表明方法有效。Aiming at video monitoring system with a static camera indoors ,an approach is presented in this paper,which uses a self- adaptive background subtraction method to update background.Mter exploiting HMMD color space for shadow suppression,we intro- duce an improved Region Growing method for location of moving object.The improved method is able to separate each moving object and get center of them. The experimental results show the effectiveness of our method.
