Combining Visual and Textual Features for Semantic Segmentation of Historical Newspapers

Abstract: The massive amounts of digitized historical documents acquired over the last decades naturally lend themselves to automatic processing and exploration. Research work seeking to automatically process facsimiles and extract information thereby are multiplying with, as a first essential step, document layout analysis. If the identification and categorization of segments of interest in document images have seen significant progress over the last years thanks to deep learning techniques, many challenges remain with, among others, the use of finer-grained segmentation typologies and the consideration of complex, heterogeneous documents such as historical newspapers. Besides, most approaches consider visual features only, ignoring textual signal. In this context, we introduce a multimodal approach for the semantic segmentation of historical newspapers that combines visual and textual features. Based on a series of experiments on diachronic Swiss and Luxembourgish newspapers, we investigate, among others, the predictive power of visual and textual features and their capacity to generalize across time and sources. Results show consistent improvement of multimodal models in comparison to a strong visual baseline, as well as better robustness to high material variance.

Detection and Reconstruction of East Asian Layout Features in a Fixed Format Document

Abstract: Detection of East Asian layout features and reconstruction of East Asian layout features is provided. Vertically written text in the fixed format document is detected and rotated for layout analysis. After layout analysis, the rotated text is rotated back and restructured in a flow format document. When a plurality of characters is written horizontally in a vertical line of text, vertically overlapping text runs are detected, designated as horizontal-in-vertical text, and are restructured as horizontal-in-vertical text in a flow format document. Lines of text are analyzed for attributes of a ruby line and are designated as ruby text, associated with corresponding text in a ruby base line, and restructured as ruby text in a flow format document. Text in a fixed format document is analyzed for detection of a particular East Asian language so that a font for the language is designated in a flow format document.

PDF document recognition method

Abstract: The invention discloses a PDF document recognition method The method comprises the steps as follows: S1: analyzing path objects in a PDF document, and recognizing forms in the PDF document; S2: analyzing text objects outside table areas in the PDF document, and recognizing text content in the PDF document; S3: writing recognition results into a temporary file, or writing the recognition results into a PDF file in the form of an attachment By the aid of the PDF document recognition method, objects such as the forms, paragraphs, titles, lists and the like in the PDF document can be recognized, so that the PDF document can be edited with one paragraph as the unit, labels can be added to the PDF document conveniently, the reading order can be determined, and persons with dysopia can read conveniently; meanwhile, documents in other formats can be exported according to the recognition results, so that users can read and edit the PDF document conveniently

Form layout method and system

Abstract: A form layout system includes a form layout tool that provides a flexible way to lay out forms on a web page. The form layout tool configures a web configuration file with the location of form layout styles, and uses the form layout styles, a number of columns, a number of fields, and a “size” of each field to include in the component of a page layout to create a page layout for a target application. The form layout tool generates a revised application page with the created page layout by applying the form layout style to the created page layout.

Image processing system for transferring electronic document and paper document as single mail

Abstract: An image processing system has a scanner for reading image information of a sheet, on which a first instruction for transferring image information of an electronic document and image information of a paper document to an arbitrary program at a first terminal as a single transferred document and a second instruction for starting an arbitrary second terminal for creating the electronic document, together with the image information of the paper document, a function for starting the program at the second terminal to create the image information of the electronic document on the basis of the second instruction, and a function for transferring the image information of the paper document and the image information of the electronic document as a single transferred document to the first terminal on the basis of the first instruction.
