Abstract

An image-based character recognition method is characterized by comprising steps as follows: an acquired image is divided into multiple areas; character areas in the multiple areas are detected to acquire the position information of the character areas and types of characters in the character areas; the character areas are screened to determine the to-be-recognized character area; on the basis ofthe types of characters in the to-be-recognized character area, characters in the to-be-recognized character area are recognized by use of a designated recognition model.

Description

technical field [0001] The invention relates to image processing, in particular to an image-based character recognition method. Background technique [0002] Optical Character Recognition (OCR) is to convert the text of various bills, newspapers, books, manuscripts and other printed materials into image information through optical input methods such as scanning and taking pictures, and then use text recognition technology to convert the image information into Computer input techniques that can be used. Optical character recognition technology has always been an important technical means to assist people in image recognition, document reading, analysis and processing, and is widely used in banking, finance, insurance, taxation, public security, border inspection, logistics, auditing and other industries. The related automation process has greatly reduced the hardware and manpower required for work, and greatly improved work efficiency. [0003] An OCR system is generally di...
