2010年ICIP最新文章关于图像复原，提出了2D NHA算法，实验证明了该算法的优越性能。-In this study, we develop a technique for image restoration

The proposed method is based on the 2D non-harmonic analy-

sis (2D NHA). The 2D NHA algorithm assigns an initial value

by using the spectrum of the maximum amplitude, which is

obtained by FFT. This value is converged to a global min-

imum by using the steepest descent method and Newton’s

method. And, an image recovery method was proposed by

improving the cost function of 2D NHA as excluding the

missing region. To verify the effi cacy of the proposed method

simulation is carried out using a damaged image. The simula-

tion results show that a high-quality image is obtained when

the missing region is consist of periodicity. In both the ob-

jective and the subjective comparisons, the qualities of the

images recovered using the proposed method are the most fa-

vorable in all cases.
