摘    要:针对视频序列中运动对象分割问题,提出一种改进的混合高斯模型分割算法.该算法首先由混合高斯模型得到前景,之后用当前帧的前景区域与上一帧对应位置做差,区分出实际变化区域及误检区域并为误检区域赋予较大的更新速率,从而有效地改善了长时间静止物体转为运动后留下的"鬼影"及光线突变导致的大面积误检情况.采用阴影抑制和形态学滤波使得前景目标分割的性能得到有效的提高.实验表明,本算法能够迅速响应实际场景的变化,准确分割出运动对象.

关 键 词:运动检测  混合高斯模型  鬼影  光线突变  阴影消除

Abstract:Aimed at the moving objects segmentation, an algorithm based on improved Gaussian mixture model (GMM) is presented in this paper. The algorithm detects foreground by GMM and classifies it into real changed area and false alarm area. The model sets the update rate in false alarm area quicker than other area to solve "ghost" and sudden illumination change problems due to sudden moving of a motionless object. The performance can be effectively improved with morphology filtering and shadow removal. Experimental results indicate that this algorithm can respond to real scenes quickly, and segment moving objects accurately.
Keywords:moving objects detection  GMM  ghost  sudden illumination change  shadow removal
