基于麦积山石窟文物的图像修复算法探究

Research on Image Restoration Algorithm Based on Maijishan Grottoes

针对图像修复算法易于修复自然图像,而对旧照片的复原和文物修复较为困难这一实际问题,分析了目前几种图像修复算法修复多色图像和文物时存在的局限性及亟待解决的问题,然后通过仿真实验表明,算法无法修复麦积山石窟单色像塑,修复效果不尽合理。重点分析了其不能修复单色文物图像的原因,最后得出这几种图像修复算法的适用性有限。这将为麦积山石窟数字化修复工作开创先例,并为研究工作者改进图像修复算法提供了理论基础,以供读者参阅。

The digital image inpainting technique is a technique of repairing a partially damaged or missing image in an undetectable way.It fills the missing part of an image to mak it look natural after repairing by employing information of the undamaged part according to some rules.Although it is easy to be repaired for natural images in the process of image restoration,the rehabilitation of the old photos and restoration of cultural relics is difficult because of two factors of image inpainting algorithm and murals itself.The paper discusses the limitations of image inpaniting algorithm and what problems must to be solved.Finally,the paper proposes that algorithm meet a new challenge in the Maijishan Grottoes repairing which offers a theoretical basis.
