Problems solved by technology
[0004] However, in practical applications, segmentation errors are prone to occur in the process of segmenting line character images into individual character images, which will affect the accuracy of line character recognition results
In particular, for some complex artistic characters or scribbled handwritten characters, there is often a situation where characters are glued together in the line character image, which will increase the difficulty of segmenting the line character image into single-character images, thereby increasing the The error rate corresponding to the segmentation error

Description
technical field [0001] The present invention relates to the technical field of OCR (Optical Character Recognition, Optical Character Recognition), in particular to a character recognition method and device, and a character recognition device. Background technique [0002] With the development of the mobile Internet, the application scenarios of OCR technology have gradually penetrated into the daily life of users from traditional office areas (such as zip codes, book scanning and document faxing). , through OCR technology, the translated Chinese dish names can be displayed on the screen; or, through OCR technology, library books can be converted into e-books, etc. [0003] The current OCR technology can obtain a line of character images from an original image containing characters, and perform character recognition on the line of character images, so as to convert the line of character images into text. The character recognition process for the line of character images may ...
