Problems solved by technology

In addition, in the layout document, the composite graph is composed of multiple sub-images, a large number of path operations, text primitives and other sub-objects, which cannot be correctly extracted as a complete composite graph in the layout structure analysis of reverse engineering
Therefore, the layout document not only requires a large number of paths to describe, resulting in a large degree of redundancy, but also is not conducive to the normal display of composite graphs when the layout document is streamlined, and it is difficult to meet the growing real needs of digital reading

Abstract

An extraction device for the composite graph in a fixed layout document comprising: a document parsing unit, for parsing the fixed layout document, and determining the primitives of the fixed layout document and their types; a layer generation unit, for extracting text primitives so as to form a text layer, and using the rest non-text primitives to form a non-text layer; a page analysis unit, for processing the text layer and the non-text layer with page analyses respectively; a block generation unit, for generating a text block in the text layer and a graph block in the non-text layer; a correlation block determination unit, for determining text blocks correlating to every graph block and merging those correlated text blocks and graph blocks into a composite graph block; an identifier storage unit, for storing the identifiers of all the primitives contained in the composite graph block.

Description

technical field [0001] The present invention relates to the technical field of format conversion of electronic documents, in particular to a device for extracting composite images in formatted documents and a method for extracting composite images in formatted documents. Background technique [0002] To convert paper documents into electronic documents, most of them use scanner scanning or camera shooting to obtain digital images of documents, and after a series of image processing, the characters are segmented out and input into OCR (Optical Character Recognition, Optical Character Recognition )system. The layout documents directly generated by document processing software, such as typesetting software, are replacing the image documents converted from paper documents as the main source of documents for digital publications. [0003] The automatic extraction of structural information mainly includes layout analysis and layout understanding, and its research is limited to th...
