摘要
首先利用统计的方法得到背景模型,并实时地对背景模型更新,以适应光线变化和场景本身的变化;减背景操作后,用形态学方法和检测连通域面积进行后处理,消除噪声和背景扰动带来的影响;最后在HSV色度空间下检测阴影,得到准确的运动目标。
A statistical method is used to obtain the background model, which is updated real time in order to adapt to illumination changes and scene changes. After the threshold operation, morphologic operation and connected region area measurement are introduced to solve the background disturbance problem. Finally, the shadow is detected using HSV color space information and gets exact moving objects.
