Problems solved by technology

[0004] However, it can be seen from the above that due to the nature of the paper itself, the image to be recognized will be different from the idealized image, and there will be some noise such as dirt, wrinkles, distortion, and pattern interference, which will seriously affect the accuracy of character recognition

Abstract

The invention provides a paper character recognition method and device, electronic equipment and a storage medium. The method comprises the steps: firstly obtaining a to-be-recognized image of paper with to-be-recognized characters; then, determining a first area image covering the character to be recognized in the image to be recognized by utilizing an image target positioning model, and cuttingout the first area image from the image to be recognized; and performing denoising processing on the first area image to obtain a denoised image. And finally, identifying the to-be-identified character in the denoised image by using a character recognition model to obtain an recognition result. Therefore, the paper character recognition method provided by the invention can eliminate the influenceof various noises in the image on the character recognition accuracy by de-noising the image with the to-be-recognized character, thereby improving the character recognition accuracy.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to a paper character recognition method, device, electronic equipment and storage medium. Background technique [0002] Usually, in order to enhance the interest and appreciation of reading while displaying text information, some fancy effects such as background patterns and frame patterns are added to paper documents and icons used for displaying text information. The carrier of paper documents, icons, etc. is paper. Since paper is naturally wrinkled, easy to fold, and easy to dirty, it is necessary to use The computer recognizes the characters on the paper. [0003] Usually, pictures to be recognized are obtained by taking pictures or scanning paper, and the pictures to be recognized contain characters to be recognized. The character area is cropped to reduce the scope of image recognition. Then a character recognition tool is used to recognize the charac...
