Abstract

The invention relates to a table parsing method and device in a document image. The method comprises: detecting a table area in a to-be-parsed document image by using a pre-trained table detection model; detecting an internal character block included by the table area by using a pre-trained character detection model; determining a spatial structure of the table; and according to the spatial structure of the table, carrying out character identification on the character block in each table cell to obtain an editable structural data by parsing. The table parsing method and device can be applied to various tables like a lined table, a line-free table, or a black-and-white table and a simple and effective solution is provided for table parsing in the document image.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a table analysis method and device in document images. Background technique [0002] In recent years, with the continuous improvement of the digitization of information, the amount of data in the form of document images has shown a trend of becoming massive. Extract information from document images to form structured data, which can be used to better build indexes, facilitate search, and can be used in scientific research, engineering, statistics, strategy formulation, market research, etc. to provide quantitative data. [0003] As the most streamlined expression of data record summary, table is the basis of data analysis. Automatically identify these document image table data, and restore the table content in the picture to structured data, which can undoubtedly improve the efficiency of data collection. [0004] Generally, there are two types of tables in a document, ...
