Problems solved by technology

[0004] Under normal circumstances, the method based on Adaboost is mostly used to identify text areas. This method mainly uses artificially designed features for text area recognition. Due to the error of artificially designed features, the accuracy of text area recognition using this method is not high.

Abstract

The present disclosure relates to a method, a device and a computer-readable storage medium for identifying text regions. Using this method, first, the feature information of the image to be recognized is input into the character area recognition model, and the first probability and the second probability of each first image region in the image to be recognized are obtained, and then, according to each first image The first probability of the region is to filter out the image region containing text, and then, on the basis of the screened image region containing text, further analyze the second probability of the image region to determine whether the image region is adjacent to it The image areas are merged, and finally, according to the merged image area, the text area in the image to be recognized is determined. Therefore, by determining the first probability and the second probability of each first image region in the image to be recognized, the character region can be directly calculated, which provides a character region recognition method with high accuracy and fast recognition speed.

Description

technical field [0001] The present disclosure relates to the field of image processing, and in particular, to a method, device and computer-readable storage medium for recognizing text regions. Background technique [0002] With the rapid development of Internet technology, there are more and more pictures on the Internet, causing inconvenience to users in obtaining desired pictures. Because the picture contains not only pictures, but also some text, people tend to search for the text in the picture to filter out the desired picture. Driven by this trend, OCR (Optical Character Recognition, Optical Character Recognition) technology came into being pregnancy. [0003] OCR refers to the technology of recognizing optical characters through image processing and pattern recognition technology. It generally includes two stages: text area recognition and text recognition. Among them, text area recognition is used to identify the position of text in the image. Text recognition is ...
