摘要
结合计算机图形学与数字图像处理的知识,提出直接在运动方向上建立点扩展函数的算法,并利用霍夫变换检测运动参数。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。文中给出了详细的算法及实验结果。
This paper provides a method to produce the PSF of the image blurred by motion at arbitrary direction to restore the image accurately and detects the motion parameter through frequency spectrum analysis using the knowledge of digital image processing and computer graphics.It solves the problem that it isn't accurate to restore images in the frequency domain.The algorithm and results are provided in the paper.
