摘　　要：利用图像去雾的思想将图像增强与物理模型有机结合起来,对模型中的未知参数进行准确估计,其中采用边缘保持滤波获取介质透射率,结合高斯滤波和直方图统计确定大气光强度.最后通过图像本身特征来设定控制参量,提高算法的适应能力原始的仿生彩色图像增强算法存在边缘效应和缺乏自适应性等不足.jThe image enhancement and physical model are combined with the idea of image, and theunknown parameters in the model are estimated accurately. The edge-preselw-ing filter is used to obtainthe transmission of the media, and the intensity of the atmosphere is detemlined by combining Gaussianfilter and histogram. Finally, the control parameters are set up by the characteristics of the image, andthe adaptation ability of the algorithm is improved.
