| 摘 要： | 提出了一种新的红外图像的统计模型,它是由高斯和广义Gamma分布复合产生的,对太阳散射、背景热辐射以及闪烁影响都可以进行准确的描述。该模型可以推导出统计矩的闭合表达式,而且取特定的参数值,模型可以变为几类常用的简单模型。模型的参数可基于统计矩估计得到,然后再根据模型实现对图像的合理分割。

| Abstract: | A new statistical model for infrared image is presented, which combined Gauss-pdf and generalized Gamma-pdf. The statistical moments of the model has closed form expressions. Models in common use also can be derived from it when the parameters are set to some specific values, so in this aspect it's generalized form of the statistical model for infrared image. The estimation of parameters can be done via the statistical moments. Furthermore, the infrared image can be segmented properly based on the model. |
