Abstract

The invention discloses a method for character recognition based on a convolutional neural network. The method comprises the following steps: determining a target image to be recognized for character; locating character information in the target image, and extracting each character; Each character of the target image is obtained to obtain multiple unigrams of the target image; each unigram is input into the pre-trained target convolutional neural network, and forward propagation is performed to obtain the text recognition result of each unigram. Applying the technical solution provided by the embodiment of the present invention, the target convolutional neural network is obtained through training a large number of unigram samples, which improves the character recognition rate of the unigram and improves the generalization ability. The invention also discloses a single-character picture and character recognition device based on a convolutional neural network, which has corresponding technical effects.

Description

technical field [0001] The present invention relates to the field of computer application technology, in particular to a convolutional neural network-based method and device for recognizing single-character pictures and characters. Background technique [0002] With the rapid development of computer technology, pattern recognition technology has also been developed rapidly. Character recognition has always been one of the important research topics in the field of pattern recognition. [0003] Characters separated in images often contain deformations, such as rotation, twisting, skewing, etc. The existing character recognition method is to correct the deformed characters by applying nonlinear transformation to the character lattice to reduce the intra-class variance according to the structural characteristics of the characters. For characters containing noise, filter algorithms such as median filtering and Gaussian filtering are used to denoise them. Then the processed char...
