摘　　要：视频运动目标检测具有十分重要的应用价值,其核心问题是目标检测算法,针对当前视频运动目标检测算法检测性能较差的问题,提出了一种改进高斯混合模型的视频运动目标检测算法。首先对传统高斯混合模型更新率进行改进,以适应外界环境的变化,然后引入三帧差分法实现了对背景模型的选择性更新,最后采用仿真实验测试算法的性能。实验结果表明,本文算法实现简单,可以对视频运动目标进行完整检测,相对于传统高斯混合模型具有更强的鲁棒性,而且检测速度更快。It has very important application value of video moving object detection,the core issue is to target detection algorithm,in view of poor performance in the current video moving object detection algorithm,this paper proposes a video moving object detection algorithm based on improved Gauss mixture model algorithm. Firstly,updating rate of the traditional Gauss mixture model was improved to adapt to the changes in the external environment,and then three frame difference method is introduced to achieve the selectivity for background model updating,finally the simulation experiment is adopt to test the performance of algorithm. The experimental results show that,the proposed algorithm is simple,can realize the detection of video moving objects completely,and has stronger robustness than the traditional Gauss mixture model and faster detection speed.
