关于学习混合高斯背景建模，其是基于像素样本统计信息的背景表示方法，利用像素在较长时间内大量样本值的概率密度等统计信息(如模式数量、每个模式的均值和标准差)表示背景。(Study on the mixed Gauss background modeling, the representation method of pixel sample statistics based on the background, the probability density statistics such as a large number of samples by the pixel value in the longer term (such as mean and standard mode number, each mode difference) background.)
