该算法用图像的高频子带信息优化了Laplace图构造，并用争议区域的进一步划分取代了Random-Walk中直接将最大到达概率所在的标签赋给待标定数据的方法。

Study of segmentation of surveillance objects with motionThe camera noise statistical characteristic is approximated as Gauss or Laplace distribution, then an error probability is set and a threshold is determined. According to the hypothesis test theory, a constructed statistic can judge whether an object is moved or not.

二、以运动物体作为监控对象的分割研究将噪声分布近似为Gauss分布或Laplace分布，再设定误判概率进而确定一个阈值就可以利用假设检验的思想，构成统计量对不同对象判断其运动与否。
