摘要
视频序列中连续两帧纯背景图像的帧间差服从高斯分布.利用高斯随机变量的峰态和偏态系数的有关性质构造了一种背景子块与目标子块的分块检测算法,并将多分辨率分析的思想引入其中.对帧差图像进行分级分块处理,构造并完善了分级分块背景重建算法,完成了相应的计算机仿真实验.实验结果表明,该算法能快速、有效的获得背景图像.
Abstract
In the video sequence,the difference of consecutive image is Gauss.A detection approach of background and target block was proposed which was constructed by characters of the kurtosis and deflection of Gaussian random variable.And the idea of multi-resolution was inducted to grade and block the different image. An approach of background estimation based on grade and block is constructed.The simulation was done by computer.The experimenting result of this method was valid and fast.
