一种结合结构和纹理特征修复敦煌壁画的方法

Dunhuang Murals Inpainting with Integrating Structure and Texture Features

敦煌莫高窟艺术是集建筑、彩塑、壁画于一体的艺术.对莫高窟壁画要科学的、合理的保护和修复.文章根据敦煌壁画内容的特征,用户可以选择相应的纹理因子和结构因子权重,并通过优先度函数来确定填充顺序.在选取与待填充块最相似的匹配块时,以两者之间颜色差别的纹理合成算法为原形,充分考虑了结构的差别,提出了同时以颜色和梯度作为衡量两者之间的相似性量度的纹理合成算法.实验结果表明,对有刮痕和大的剥落块等破损区域的壁画,该方法都有很好的修复效果,并且保留了壁画原有的艺术风格.

According to the feature of murals contents, the users can select related texture term and structure term weight, and the filling order is determined through computing patch priorities. To select a patch which is most similar to the patch to be filled is considered texture synthesis algorithm as the primary form based on the difference of color, and the difference between the structures. The experimental results showed that parts of murals with scratches and large flaking patch can he inpainting effectively with the method, and retain murals original artistic style.
