一种基于三层圆柱体码本模型的前景检测算法
Foreground Detection Algorithm Based on Three-Layers-Cylinder Codebook Model
针对经典码本模型算法无法消除运动目标阴影和码本模型参数难以调节的问题，提出一种在YUV空间下的三层圆柱体码本模型算法。该算法根据运动阴影与背景相比色度相同亮度偏低的特点，在模型底部构建了阴影背景模型；根据光照变化的特点，在模型顶部构建高亮背景模型；并对亮度分量进行高斯建模，用以调节码本模型参数。实验结果表明：采用该模型和参数调节方法能较好的去除阴影和适应光照的变化，而且具有良好的检测精度和鲁棒性，适用于复杂环境下的前景检测。
onsidering that the classic codebook model algorithm can not eliminate the shadow of moving objects and hard to adjust the model parameters, a foreground detection algorithm based on three-layers-cylinder codebook model is proposed. Experimental results illustrate that the proposed method not only has better effect on shadow removal but also show more adaptability on mutation of luminance. Furthermore it provides better detection precision and robustness in complex environment conditions.(10 Points, Times New Roman)
