摘要
针对高斯混合模型存在背景更新收敛性差、易受环境噪声和光照突变影响、易产生虚假目标等问题,提出一种基于高斯混合模型的改进算法,用于视频中行人目标检测。通过将帧差法引入高斯混合模型,快速区分背景区域和运动目标区域,从而提取前景中完整的行人目标。结合视频帧边缘和边缘帧差信息,采用多种模型更新率,提高高斯混合模型对复杂背景的自适应性和快速收敛性,从而消除环境噪声和光照突变的影响,避免检测出虚假目标。实验结果表明,相比传统高斯混合模型,该方法可以有效去除噪声和光照的干扰,收敛性更佳、行人检测效果更鲁棒。
For the Gaussian mixture model(GMM)was weak in convergence,sensitive to ambient noise and sudden light change,and prone to detect false target,this paper proposed an improved algorithm based on GMM for moving pedestrian detection in videos.It introduced the information of frame difference into GMM background model,which quickly distinguished the background region and the moving object region,to extract the complete moving pedestrian in the foreground.Then,the background model mixed with the edge detection and edge frame difference in the video,and adopted different rates of background updating.It improved the adaptability and accelerated the speed of convergence,to eliminate the affection of noise and illumination change,and also removed the false target.The experimental results show that the improved algorithm is more efficient than traditional GMM to remove the influence of noise and illumination,and has better convergence and robustness in the pedestrian object detection.
