Abstract

Ancient manuscript analysis is to aid historian to classify, annotate and judge the authenticity of larger collections of ancient manuscripts. Previous method was to examine the composition of manuscript such as paper support or inks by destructive sampling and chemical analysis. The aim of this paper is to present an image-based non-destructive and non-invasive method to analyze ancient manuscripts. A new unsupervised classification algorithm was designed to distinguish different type of paper support without any priori knowledge. The advantage of this classifier comparing with traditional methods such as K-means is that no pre-defined class number is needed. This is critical important in this application because no any priori knowledge about these manuscript was available before classifying. We presented the multi-model based framework of unsupervised classification, so that different statistical models can be applied to the same flow chart for different applications. This classifier enables us to study the statistical properties of these manuscripts, which is very hard to characterize due to the decay materials and bad resolutions. We evaluated this unsupervised classification performance by a specially developed algorithm. Experiment results show the potential of our unsupervised classification method in ancient manuscript analysis.
