Abstract

The invention discloses an image recognition method and system and a data processing method. The image recognition method comprises the following steps: acquiring a table image; processing the table image to obtain table data corresponding to the table image, wherein the table data comprises text information in cells in the table image and the structural relation between the cells; processing the table data by using a table recognition model to obtain keywords and structure types of the keywords in the table image, the table recognition model being used for obtaining the table data, inputting the table data to the coding network to obtain vectors corresponding to the table data, inputting the vectors to the feature extraction network to obtain features of the table data, and inputting the features of the table data into a classification network to obtain keywords and structure types of the keywords. According to the method and the system, the technical problem of relatively low recognition accuracy of keywords in table images in related arts is solved.

Description

technical field [0001] The present application relates to the field of image recognition, in particular, to an image recognition method and system, and a data processing method. Background technique [0002] A table is a data visualization method that visually shows how data is organized. Currently, OCR (Optical Character Recognition, Optical Character Recognition) is commonly used to recognize form images. However, the text blocks output by this method lack the original data structure information, resulting in low recognition accuracy. [0003] For the above problems, no effective solution has been proposed yet. Contents of the invention [0004] Embodiments of the present application provide an image recognition method and system, and a data processing method to at least solve the technical problem of low recognition accuracy of keywords in form images in the related art. [0005] According to an aspect of the embodiment of the present application, an image recognition...
