Emission-line region line spread function

线扩散函数

The algorithm restores the image and the point - spread function ( PSF ) simultaneously.

该算法同时恢复了图象和点扩张函数.

Through exploration of the point spread function of the blur of uniform linear motion, a novel method based on frequency-domain algorithm for identification of motion-blur direction was presented.

本文通过深入研究匀速直线运动模糊图像的点扩展函数，提出一种识别运动模糊图像模糊方向的频域方法。
