摘要：为了更好地适应复杂背景，提出了一种基于光照不变颜色特征的多层前景检测方法。首先，提出了一种具有光照不变性的颜色模型用以解决因光照引起的颜色变化问题（如阴影抑制）；其次，使用多层背景构造方法建立了动态背景模型；最后，利用有效的权重更新方法解决了背景静止物体运动产生的虚假目标问题。实验结果表明，该前景检测方法能够适应光照变化、背景运动等复杂环境，并能够有效处理虚假目标问题。

Abstract: In order to adapt to complex background better, a photometric invariant color based multi-layer foreground detection method was proposed. Firstly, a photometric invariant color model was proposed to solve the color change problem caused by illumination (such as shadow inhibition). Secondly, a dynamic background model was constructed using a layer based method of background modeling; Thirdly, an effective weight update method was used to solve the false object problem caused by the moving of the stationary objects in the background. Experiments results show that, the foreground detection method is able to adapt complex of the environment such as inhibition illuminaition changes, background movement, and it is able to effectively deal with the false object problem.
Key words: moving target detection; photometric invariance; multi-layer background modeling; false target
