: 一种图像序列中运动目标检测的鲁棒算法 段 慧, 关 键 ( 26400 1) : 人体运动检测在计算机视觉中是一项很基本的任务, 在图像序列中检测人体运动是一种 行的方法在做运 动目标检测时, 常用的图像差分方法有着固有的缺点, 用 一种改进的图像差分方法进行目标检测, 利用 一种全局阈值分割方 法对差分图像进行二值化, 通过数学形态学计算法进行滤波, 有效地克服这些缺点实验结果表明, 此方法能很好地检测 低信噪比图像序列中的运动目标 : 图像序列; 运动检测; 图像差分; 数学形态学 : T P14 : B : 1004373X( 2007) 2211402 A Robust Method f or Moving Target Detection in Image Sequence DUA N H ui, GUA N Jian ( Naval Aer nautics Engineering Institute, Yantai, 26400 1, China) Abstract : H uman m t i n detecti n is a fundamental task f r many c mputer visi n tasks. Detecting m ving target in image sequence is a viable meth d, image difference meth d f r detecting m ving target has natural disadvantages. We use an im pr ved image difference meth d t detect m ving bject, a binary difference image can be btained thr ugh a gl bal thresh ld segmentat i n and n ise is rem ved by mathematical m rph l gy perati n. T he meth d may verc me the disadvantages. The experimental results sh w t hat this meth d can effectively detect m ving target f r m the image sequence with l w SNR.
