Abstract

The invention provides a text recognition method and device. The method comprises: determining convolutional neural network (CNN) features of a text image and obtaining an eigenvector sequence of a preset dimension; and using a recurrent neural network (RNN) to decode the eigenvector sequence of the preset dimension, and obtaining texts in the text image to be recognized. According to the technical scheme provided by embodiments of the invention, the method combines the CNN and RNN to achieve integral recognition of the text image to be recognized, so that the method avoids the problem that texts need to be separated character by character and then recognized character by character in the prior art which leads to accumulated errors, and the text recognition rate can be improved.

Description

technical field [0001] The present disclosure relates to the technical field of character recognition, in particular to a method and device for character recognition. Background technique [0002] Text recognition in natural scenes is an important field in computer vision, including two steps of text detection and text recognition. Text detection is to detect the text area where text appears in the image, and text recognition is to identify the text area. Get the corresponding text. [0003] In the related art, by dividing the text in the text area word by word, and then recognizing the text one by one, each step in the text recognition of the related art is an independent step, which easily causes cumulative errors and reduces the text recognition rate. Contents of the invention [0004] In order to overcome the problems existing in the related technologies, the embodiments of the present disclosure provide a character recognition method and device, which are used to red...
