目标检测首先利用统计的方法得到背景模型，并实时地对背景模型进行更新以适应光线变化和场景本身的变化，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，在HSV色度空间下检测阴影，得到准确的运动目标。(object detectWe use statistical methods to obtain the background model, and real-time of the background model is updated to adapt to illumination changes and scene changes, using morphological method and connected domain detection area of postprocessing, eliminating the background noise and the impact of disturbance, in the HSV color space under the shadow detection, moving target accurately.)
