摘 要: | 文章从边缘的角度出发,分析红外遥感图像质量的评价参数——边缘信号能量与调制传递函数MTF(Modulation Transfer Function)的关系。实验结果表明边缘信号能量能很好地反映MTF的变化,并针对某一特定地物建立实验室条件下边缘信号能量与MTF的数学关系模型。

Abstract: | This paper analyzes the relationship between image quality evaluation parameter of infrared remote sensing image--edge signal energy and MTF from the aspect of edge. The result of experiment shows edge signal energy can reflect the change of MTF very well and a data relation model between edge signal energy and MTF is set up for a special target in the laboratory. |
