摘要 本文介绍了图像修补和小波图像修补问题,在分别研究了小波域和空域的图像修补技术的基础上,提出在空域解决小波域的图像修补问题的思想。本文简要给出了该思想的实现依据,引入非局部方法,提出实现该思想的非局部方法。实验表明,本文方法可以得到较好的图像修补效果,显著提高图像的峰值信噪比,说明小波域修补问题在空域中解决的可行性。

Non-local Method Solving Wavelet Image
Inpainting Problem in Pixel Domain
Abstract The problem of Image inpainting and wavelet image inpainting are presented in this paper.
Based on the study of various methods to inpaint image in wavelet and pixel domain respectively,
we get an idea to solve wavelet image inpainting problem in pixel domain. Non-local method is introduced. A method using non-local method in pixel domain
is proposed to put the thought above into practice. The experiments demonstrates the method
works, and inpainting effect is good. It also illustrates the feasibility of solving wavelet image
inpainting in pixel domain.
