西安韩森寨元代墓室壁画数字化修复方法

西安韩森寨元代墓室壁画是西安地区元代时期唯一的墓室壁画资料，因诸多原因受到了严重的损坏。为了给相关学科研究提供更为直观的壁画资料和类似壁画的修复方法参考，从图像信息损失程度及损失信息与已知信息的关联性角度，对韩森寨元代墓室壁画的损坏情况和类型进行了分析，针对性地提出了一种数字化人工和自动修复相结合的壁画数字化修复方法，并基于图像块和稀疏表示模型实现了壁画的数字化自动修复算法，最终选取韩森寨甬道西壁散乐图局部作为修复实例进行了数字化修复。验证结果表明，所提方法在修复效果、修复效率、可操作性等方面均有较好表现。

Research on the Digital Restoration Method for the Murals in the Yuan Dynasty Tomb of Hansenzhai, Xi'an

In order to provide more intuitive research materials and similar methods of mural restoration for related disciplines, from the perspective of the loss degree of image information and the correlation between the loss information and the known information, the damage types of the murals in the Yuan Dynasty tomb of Hansenzhai are analyzed, a digital restoration method which combines digital manual and automatic restoration is proposed, and based on the image block and sparse representation model, the algorithm of digital automatic restoration of murals is realized. Finally, a part of the murals in the Yuan Dynasty tomb of Hansenzhai is selected as digital restoration examples. The proposed method is well verified in terms of repair effect, repair efficiency, operability.
