【摘要】 介绍了几种常用的背景提取算法,提出一种新的算法,利用图像块能量、高阶累积量建立背景约束的准则。考虑到能量块门限为定值的不足,对能量块门限进行自适应估计,实验结果表明这种算法兼顾了实时性和精确性,能有效地对静止背景进行提取。该算法得到的背景效果良好,适用于视频系统。更多还原

【Abstract】 This paper introduces some algorithms for background extraction, and presents a new algorithm for background extraction based on image block energy and high order statistic theory(HOS), and background reconstruction constraint conditions are setup. The energy block threshold has been estimated. Experimental results demonstrate that the algorithm is effective for use in real-time video monitoring system.更多还原
