| 摘 要： | 提出一种融合高斯混合模型和prewitt算子的运动目标检测算法.通过高斯混合模型拟合背景信息,利用prewitt算子提取图像的边缘特征信息,将两者融合起来.边缘信息反映了局部区域内容的结构信息,可作为颜色信息的补偿;模型保证了在线更新背景信息时的稳定性和收敛性,同时弥补了目标分割中颜色信息接近时容易导致误判的不足.实验结果表明,与一般高斯混合模型比较,本方法具有较高的分割精度,提高了目标检测的鲁棒性.

| Abstract: | A moving object detection method is proposed by combining a Gaussian mixture model with the prewitt operator.The prewitt operator is employed to extract edge information and a Gaussian mixture model is employed to update the background.Color information and edge information are integrated for segmentation.The edge information,which reflects area information,can compensate color information＇ flaw in segmentation.The method improves the abilities of convergence and stability,and also decreases commission error brought by the method only using color information.Experimental results indicate that the proposed method is superior to the traditional Gaussian mixture model. |
