Abstract

The present invention proposes a method and device for character recognition, wherein the method includes the following steps: obtaining the current character image; segmenting the character image in columns to obtain multiple character blocks and corresponding widths in the character image, and according to the multiple character blocks and Obtain the 1st to Kth standard width corresponding to the width, where K is a positive integer; obtain the blocks drawn by the user on the text image; and merge the drawn blocks according to the 1st to Kth standard widths, and merge The stroke block is identified to obtain the corresponding stroke character. According to the method of the embodiment of the present invention, the drawn blocks are dynamically merged according to multiple standard widths to obtain the corresponding drawn characters, and the inaccurate combination of broken blocks and word blocks is improved for pictographs, which greatly improves the user experience. .

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a character recognition method and device. Background technique [0002] With the rapid development and popularization of mobile terminals (such as smart phones, tablet computers, etc.), the demand for searching based on multimedia information is increasing. According to different input methods, searches are mainly divided into four types: text search, voice search, image direct search and Image OCR (Optical Character Recognition, optical character recognition) recognition search. The first three search methods have relatively large limitations. Image OCR recognition search can first extract the character blocks in the image, and then use OCR recognition to convert the text image into the corresponding text before searching. In the early research on text segmentation based on OCR recognition, remarkable results have been achieved in the segmentation of European language...
