【摘要】 图像序列中的运动区域的正确检测是一个相当重要但又非常困难的问题。采用了自适应的背景模型,并用交叉熵对差分图像阈值化,从而使分割出的运动区域更加正确。试验结果表明了本方法的有效性和鲁棒性。更多还原

【Abstract】 Motion re gion detection is a very importance but a difficult problem.This paper use an adaptive back-ground model,and use cross entropy to obtain the threshold of th e difference image.The segementation of the motion region is accurately.The re sult of experiments shows that this method is robustly and effectively.更多还原
