The invention discloses a scene text recognition method based on a compression and excitation neural network. According to the method, a natural scene image containing characters is preprocessed in an input layer to obtain a text block image, then feature extraction is carried out on the text block image through a feature extraction layer composed of a compression and excitation neural network, and then the extracted feature image is subjected to feature transformation to form a plurality of feature sequences; at the moment, each feature sequence corresponds to a receptive field of the original image, then the feature sequences are sent to a time sequence information learning layer, the time sequence information learning layer uses a double-layer bidirectional gating recurrent neural network to extract feature map time sequence information, and finally a connection time classification network CTC is used for transcription translation to obtain a prediction text. The method is high in recognition ...
