Abstract

The invention relates to a layout analysis method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring a spatial conversion feature, a position feature and an image feature of each text line in a target text image; according to the space conversion feature and the position feature of each text line, obtaining a relation coding feature of each text line, and splicing the relation coding feature of each text line and the image feature of each text line to obtain a fusion feature of each text line; and decoding the fusion feature of each text line to obtain the layout information type of each text line. The content of the text image is understood by combining the spatial conversion features and the image features instead of being based on one feature, so that the analysis result is relatively accurate. Besides, each text line is analyzed in combination with the image feature and the spatial conversion feature during analysis, and the other feature can be used as an analysis basis under the condition that one feature is wrongly recognized, so that the error-tolerant rate of layout analysis is improved.

Description

technical field [0001] The present application relates to the technical field of text and image recognition, in particular to a layout analysis method, device, computer equipment and storage medium. Background technique [0002] Text image digitization is a technology that extracts text information from text images into electronic information. In today's rapidly developing information age, text image digitization can significantly improve the efficiency of information dissemination and use. Traditional text image recognition mainly includes two stages: the layout analysis stage and the text recognition stage; among them, the layout analysis stage is used to analyze each text unit in the text (such as paragraphs in ordinary texts and test paper texts) through different strategies and methods. The location and category of the test questions in the text, etc.); the text recognition stage recognizes the text contained in each text unit, thereby completing the electronicization o...
