摘要:

针对固定摄像机条件下的视频监控问题,提出了一种基于背景相减法和混合差分法相结合的运动目标检测算法。该方法对彩色图像建立混合高斯模型,对背景模型进行实时更新;并对帧间差分法进行了改进,提出混合差分的思想。通过背景相减法和混合差分法的结合,采用形态学滤波的方法去除噪声点,检测到确切的运动目标。实验结果证明,文中提出的算法能准确地建立背景模型,既完整地提取运动目标,又适应复杂环境的变化,提高了运动目标检测的精确度和速度。

关键词: 运动目标检测, 混合高斯模型, 背景相减法, 混合差分法

Abstract:

A novel moving objects detection algorithm based on background subtraction and hybrid difference is proposed for video surveillance system with static camera.First,the mixed Gaussian model is constructed for the color images,and the background model is updated timely,then the idea of hybrid difference is presented on the basis of the adjacent frame difference,and finally the background subtraction is combined with hybrid difference to gain exact moving objects.Experimental results show that the proposed method could construct background model accurately,and that it not only gets moving objects completely,but also adapts to the complex environmental change so that both the accuracy and speed are improved.

Key words: moving objects detection;mixed Gaussian background model;background subtraction;hybrid difference
