Problems solved by technology

The steps of traditional neural network character recognition include character detection, character segmentation and character recognition. Although the use of neural network can improve the recognition effect, however, because the text on the number cloth is easily affected by the distortion of the number cloth, it cannot Complete cutting will lead to errors in the subsequent Optical Character Recognize (OCR), which will affect the accuracy of text recognition

Abstract

The invention relates to a character recognition system and a character recognition method thereof. The character recognition method includes the steps of: recognizing a character string, which includes one or more characters, in a region of interest by using a first convolutional neural network (CNN) model to generate a recognized character string; and comparing the recognized character string with a plurality of character strings in a character database to find a character string corresponding to the recognized character string, wherein each of the character strings includes one or more characters; wherein if the character string corresponding to the recognized character string is found, the recognized character string is used as a character recognition result, otherwise, using a secondCNN model to correct the recognized string and generate a new recognized character string as the character recognition result.

Description

technical field [0001] The present disclosure is about a character recognition system and its related character recognition method, especially about a convolutional neural network-based character recognition system and its related character recognition method. Background technique [0002] Driven by the popularity of sports and the needs of users, a large number of photos or videos will be recorded in each game. More and more competition units or sports websites provide athletes with photo or video search services using the characters marked on the number bib (such as numbers, etc.), so that participants can search for their own photos or videos after the game and share them on social media. group network. Generally speaking, this type of identification is carried out by computer for image analysis and processing. However, due to the relationship between the displacement and deformation of the number cloth in the photo or video, the accuracy of using a computer to identify...
