| 摘 要： | 为了减小环境温度对红外人脸图像的影响,本文提出了一种基于统计回归模型的红外人脸温度归一化方法.为了得到环境温度与红外人脸温谱图在对应像素点灰度之间的关系,将环境温度改变值和对应人脸上的温度变化值作为研究对象,利用统计回归方法对这两个对象进行二次多项式拟合即可得到环境温度变化和对应的人脸上温度变化的函数关系.通过得到的函...

| Abstract: | To reduce the impact of ambient temperatures on infrared face images,a normalization method of infrared images was proposed based on a statistical regression model.Firstly,we obtained the changes of both ambient temperatures and corresponding temperatures in face were obtained,which were used to establish a function through a second-order polynomial model.Then,the infrared images were normalized to reference ambient temperatures by the relevant function.Our experiments demonstrated that the images with temp... |
