摘要
本文在[1,2]的基础上,通过离散Fourier变换,给出了一个高频重建正则外推算法。该算法能够较好地抑制噪音干扰。其计算量和存储量较小,给出了一个计算正则参数的新方法,证明了算法的收敛性,计算机实验结果表明,该方法有良好的应用前景。
In this paper, a digital method of superesolution or hig -fequency reeonstruction is described. This method the computational complexity is also lower after proving the convergence of the regularization algorithm,some results of computer experiment are presented.
