摘要 本文提出了一种视频图像处理中基于速度场的背景估计方法。针对简单统计平均方法的不足,提出对包含运动目标区域的估计方法,和在此基础上消除运动目标遮挡影响的背景估计方法,提高了背景估计的准确性和收敛速度。 A new background estimation method based on velocity field is presented.To improve the simple statistical average method, we present a method to estimate the regions containing the moving object,based on which a background estimation method is proposed.The new method improves the quality of background estimation and decreses the convergence time.
