Digitization technologies play more and more important role in relic protection now. This article summarizes the current status of digitization technology application in relic protection. Combined with work achieved in the digitization protection, restoration and development of Dunhuang Cave recent years, the application of digitization technology in the relic protection fields such as information acquire, display, mural copy and intelligent pattern creation of Dunhttang style is introduced. Artificial Intelligence and Muir-media technology was combined with arts; many techniques were developed to resolve the problems and achieved excellent results. At the end of the article, a conclusion about achievement and experience of digitization yelic protection is drawn and some possible future direct'ions are also suggested

介绍了视觉颜色空间及其在交互式图像分割中的作用，实验分析了它的奇异性，在此基础上，考虑像素的空间和色彩分布，提出了基于区域生长法的多颜色空间、多度量准则的聚类算法和零碎区域的合并算法，颜色空间选取HSL和RGB两种，相似性度量包括了种子点、扩张点和生长区域三个方面，并用于敦煌壁画图像的分割。

This paper introduces a virtual Dunhuang mural restoration system in collaborative network environment. It describes the style of Dunhuang mural, analyzes the reasons of mural spoilage, and presents the necessity to develop a collaborative mural restoration GroupWare. It describes the components and the workflow of mural restoration in detail, solves some key technologies in the system. In the end, it introduces the system architecture, and presents the system interface and some restored results.

古代一些璧画，由于长期受外界环境，如光照、温湿度的影响，已程度不同地产生了破损，为了使人们能够欣赏到原怍的风貌，可以采用计算机来进行模拟和复原，现以敦煌莫高窟壁画为应用背景，提出了一个使破损壁画虚拟复原和湃变模拟的模型以及计算机模拟方法。它可以为复原性临摩、壁画研究以及壁画保护工作者提供参考。根据敦煌保护专家对壁面颜料成分的研究和艺术家积累的经验知识。参考目前保存得比较完好的一些壁画·通过综合利用色彩学知识、图象处理、人工智能等计算机技术。实现了把一些变色、褪色、脱落的敦煌壁画复原为初画成时金碧辉煌的景象，并摸拟出其在外界环境因素影响下渐变到现状的过程。其结果令人满意，部分成果已在德国汉诺威20OO年世界博览会上晨出。

The paper proposes a computer aided way for culture heritage protection and restoration, which is based on virtual navigation and image processing technologies. It first creates the database for the digital information of the cave construction and the mural and also provides some operations, such as insert, quev ere, for the database management. In a virtual environment of the cave, users can navigate, mark the disease area, inquiry the information about the mural monitor and analyze the environment data, and also do virtual mural restoration and shnulate the mural evolution without damaging the heritage itself. The article introduces the following technologies: virtual construction of the cave, knowledge expression of Mural interactive disease marking, object extracting, color restoration with mural knowledge, color harmonization for simulating the mural evolution, and also the functions, modules, workflow of our system.
