Analysis and Segmentation Algorithm of Dongba Pictograph Document

Dongba character is a kind of pictograph to picto-graph, phonetic character transition form. It has the charac-teristics of large differences in personalization of writing and has more variants. Because it does not have a standard, open data set, it has brought a huge obstacle to the study of Dong-ba characters. The popularization and sharing of electronic documents provides a more convenient and faster way to sample Dongba characters. Therefore, based on the projection segmentation algorithm, combined with the structure of the Dongba hieroglyphic document, we set the segmentation conditions that meet the structure of the Dongba character document, and realize the structure analysis and segmentation of the document.
