Abstract

The invention provides a semantic association character recognition method and device, and relates to the technical field of image processing. The method comprises the following steps: acquiring a to-be-recognized image, and acquiring a character template corresponding to the to-be-recognized image; calculating the similarity between the to-be-recognized image and the character template; according to the similarity, determining whether the character in the to-be-recognized image is a pre-determined character category, and when the similarity is greater than a preset value, determining that the character in the to-be-recognized image is a target character; dividing an area where the target character is located into a plurality of blocks; checking the characters in each block according to the semantic relevance to obtain a checking result; and identifying the target character according to the inspection result. The characters in the image are accurately recognized through multi-region relevance detection, so that the accuracy of character recognition is improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method and device for recognizing semantically associated characters. Background technique [0002] With the vigorous development of Internet technology, more and more pictures are displayed, transmitted or applied on the Internet, and are also applied to many fields such as education, media, and medicine. Their role cannot be replaced more and more. At the same time, a large amount of text appears in the picture, but readers can only read it but cannot edit it more conveniently. How to effectively identify the target text from the image has become a very meaningful work. Traditional text recognition methods can better recognize text and complete more accurate recognition. However, the traditional methods have very obvious limitations. First of all, the forms of characters are very diverse and often contain very complex backgrounds. Traditional recognition me...
