Abstract
Embodiments of the present application provide a character recognition method and device. The method includes obtaining a target image to be analyzed which contains a character (S); inputting the target image into a pre-trained deep neural network to determine a feature map corresponding to a character region of the target image (S); and performing character recognition on the feature map corresponding to the character region by the deep neural network to obtain the character contained in the target image (S). The deep neural network is obtained by training with sample images, a result of labeling character regions in the sample images, and characters contained in the sample images. The method can improve the accuracy of character recognition.
