摘要:

研究人员持续进行确证性测试,以根据书写表面的物理材料对古代历史文献进行分类。然而,这些通常在现场进行的测试需要实际接触手稿实物。这些程序涉及大量的时间和成本,并可能损坏手稿。开发一种仅使用数字图像对此类文献进行分类的技术将非常有用且高效。为了解决这一问题,本研究使用著名历史收藏——死海古卷的图像,提出了一种对手稿材料进行分类的新方法。所提出的分类器使用二维傅里叶变换来识别手稿表面内的模式。将采用该变换的二元分类系统与多数投票过程相结合,被证明对该分类任务有效。这项初步研究表明,对于由羊皮纸或莎草纸材料制成的有限数量的手稿,分类成功率高达97%。基于傅里叶空间网格表示的特征向量优于同心傅里叶空间格式。

英文摘要:

Researchers continually perform corroborative tests to classify ancient historical documents based on the physical materials of their writing surfaces. However, these tests, often performed on-site, requires actual access to the manuscript objects. The procedures involve a considerable amount of time and cost, and can damage the manuscripts. Developing a technique to classify such documents using only digital images can be very useful and efficient. In order to tackle this problem, this study uses images of a famous historical collection, the Dead Sea Scrolls, to propose a novel method to classify the materials of the manuscripts. The proposed classifier uses the two-dimensional Fourier Transform to identify patterns within the manuscript surfaces. Combining a binary classification system employing the transform with a majority voting process is shown to be effective for this classification task. This pilot study shows a successful classification percentage of up to 97% for a confined amount of manuscripts produced from either parchment or papyrus material. Feature vectors based on Fourier-space grid representation outperformed a concentric Fourier-space format.
