摘要  为了能够在任意直线方向上精确地恢复出原图像,结合计算机图形学的知识,提出了一种设置空间域点扩展函数(PSF)的方法,直接在空间域作图像恢复.解决了由于运动模糊图像频谱存在零值,导致在频域中不能精确恢复图像的问题.并给出了详细的算法及实验结果. The paper provides an algorithm to produce PSF(Point Spread Functron) in the time domain to do the restoration of images at arbitrary direction, using the knowledge of computer graphics. It solves the problem that it is not accurate to restore images in the frequency domain because of the particularity of the frequency spectrum. The paper provides the algorithm and the simulation result.
