【摘要】 本文提出一种固定背景下的运动目标自动分割技术．首先，提出了一种新的运动变化检测方案．然后利用递归高阶统计的方法从高斯噪声中提取运动变化．同传统的高阶统计方法相比，递归高阶统计由于利用前ｎ 帧的图像信息，所以能够更有效地抑制噪声，检测小目标，并且分割效果较好．更多还原

【Abstract】 A moving object detection method in video sequence was proposed, which is considered a fixed camera model. Firstly, a new method was presented for detection of changes of motion. After the change detection, the recursive higher order mothod was used to extract the change from the Gaussian noise. Compared with the classical higher order statistics method, the recursive higher order statistics method uses the former n images information, so it can obtain better estimates of HOS to reduce the effect of additive noise and detect the small object and perform well on segmetation.更多还原
