付立叶级数滤波法在测定成象系统调制传递函数中的应用

The Application of Fourier Series Smoothing Method in Determining Modulation Transfer Function of Imaging System

本文着重研究付立叶级数滤波法在测定成象系统调制传递函数中对刀刃曲线的滤波。试验结果表明:付立叶级数滤波法是一种行之有效的方法,并便利于用调制传递函数评价影象质量。

In this paper,the application of Fourier Series smoothing edge curves in determining modulation transfer function of imaging system is discussed. The results show that Fourier Series Smoothing method is not only an efficient method,but also is easy to estimate image quality using modulation transfer function.
