视频监控系统中运动目标的检测和阴影抑制

提出了一种室内静止摄像机条件下的运动目标检测和阴影抑制方法。该方法采用一种自适应的背景估计方法来实时更新背景，用基于概率分类法检测运动目标，并在联合HMMD色彩空间和光度特征来抑制阴影之后，用Sobel边缘检测来修正运动目标。实验结果表明，该方法能够有效地检测运动目标和抑制阴影。

Moving object detection and shadow suppression in video monitoring system

An approach to detect moving object and suppress shadow with a static camera indoors is presented in this paper，which uses a self-adaptive background subtraction method to update background and detects moving object based on the classification of probability，associates with HMMD color space and luminosity characteristic for shadow suppression，and then Sobel’s edge-detecting algorithm is used to amend moving object The experimental results show that the method is effective in detecting moving targets and suppressing shadow.
