摘要
从刀刃曲线求取ＭＴＦ的基本理论入手，介绍了从数字影像中提取刀刃曲线的方法，简要说明了图像在频率域和空间域中的恢复过程。实验证明，ＭＴＦ理论在影像恢复中有很大的应用潜力。
The theory of modulation transfer function(MTF) has an important status in restoration technique. Generally, it is not feasible to resolve MTF because the MTF depends on a very large number of time and space varying factors. Therefore a approximate MTF is often used in image restoration. In this paper, the authors describes a model of computing MTF from edge curve based on original images, and the methods of extracting edge curve and image restoration processing both in frequency domain and spatial domain are explained. The experiments confirm that MTF theory has great potentiality in image restoration.
