摘　　要：传统模糊图像复原(traditional blurred lmage restoration,TBIR)理论指明了点扩散函数(pointspread function,PSF)和运动模糊图像频谱特征之间的关系,在传统复原算法的基础上,运用一种提取PSF参数的改进算法,就是借助对模糊图像的傅氏频谱图进行Radon变换来估计PSF的参数。实验结果表明,该算法比以前的传统算法更为精确。The theory of Traditional Blurred Image Restoration(TBIR)indicates the relationship between point spread function(PSF)and spectral characteristics of motion blur image restoration.In addition to the traditional restoration algorithms,an improved algorithm for determination of PSF parameters is proposed based on the Fourier frequency spectrum of TBIR by Radon transform.The experiment results show that this algorithm could be more accurate than the traditional ones.
