Abstract

The present disclosure relates to a character recognition method and device. The method includes: acquiring an image of a line of characters to be recognized; identifying a character division line in the image of a line of characters to be recognized through image features; segmenting the image of a line of characters to be recognized according to the character division line to obtain a character segmentation image. This technical solution uses image features to identify the character segmentation line in the image of the character line to be recognized, and then uses the character segmentation line to perform character segmentation on the image of the character line to be recognized, which can effectively improve the robustness of the segmentation and eliminate the influence of noise and light .

Description

technical field [0001] The present disclosure relates to the technical field of character recognition, in particular to a character recognition method and device. Background technique [0002] Optical character recognition (OCR) is to use the method of image recognition to recognize the text on the scanned document. The general steps are: image preprocessing, line segmentation, single character segmentation, single character feature extraction and recognition, language model post-processing and other steps. The existing single-character segmentation method is based on the method of projection graph and connected domain, which is easily affected by noise, and the effect of single-character segmentation is not good. Contents of the invention [0003] Embodiments of the present disclosure provide a character recognition method and device. Described technical scheme is as follows: [0004] According to a first aspect of an embodiment of the present disclosure, a character re...
