中文摘要： 贝叶经是记载南传佛教、傣族民族历史文化的原始文献资料，是代表亚洲经典文化与艺术的珍贵典籍，具有非常高的宗教、民族历史文化研究价值。然而，贝叶经的保存现状堪忧，流散民间的贝叶经老化损毁严重，对其展开保护和整理工作迫在眉睫。目前国内贝叶经保护研究主要由人文科学、社会科学相关学科的研究人员进行。因此，本项目拟针对贝叶经数字化保护的应用需求，运用图像处理技术及模式识别技术研究贝叶经数字化保护的关键问题：（1）复杂背景的贝叶经图像自适应增强及二值化；（2）扭曲文本行及字符跨行及重叠背景下的贝叶经文本行分割；（3）跨行及粘连的贝叶经老傣文字符分割；（4）贝叶经老傣文脱机字符特征提取与识别。本项目的研究将为国内现有贝叶经保护提供具有创新性的研究思路和技术方法，推进贝叶经及其他少数民族文化遗产的保护和数字化工作。

英文摘要： Palm leaf manuscripts are the original documents which were recorded the Theravada Buddhism, and the national history and culture of the Dai nationality. In addition, these manuscripts are regarded as the precious documents on behalf of the Asian classical culture and the arts. Consequently, palm leaf manuscripts have a relatively high research value in the study of religious, ethnic history and culture. However, the conservation status of palm leaf manuscripts is worrying. The reason is that palm leaf manuscripts are nearing the end of their natural lifetime and are facing destruction. So we should take measures to protect them as soon as possible. At present, the preservation researches are done by researchers whose majors are the humanities, social science in China. Therefore, this project aims to solve the requirement of digital preservation technology for the palm leaf manuscripts by researching the key digital preservation technology using image processing and pattern recognition technologies, including (1)Adaptive algorithms for the image enhancement and binarization of the palm leaf manuscripts with complex background; (2) Text Line Segmentation of the palm leaf manuscripts with distorting lines with crossing and overlapping components;(3) Character segmentation of the palm leaf manuscripts with overlapping and touching components; (4) Offline Old-Dai character recognition for the palm leaf manuscripts. The research of this project, which is a breakthrough and innovation of domestic research perspective and methods in palm leaf manuscripts protection study, provide new ideas and methods for the protection of palm leaf manuscripts and other ethnic minority cultural heritage. Therefore, it has important practical significance and research value for the protection, development and inheritance of the palm leaf culture.
