Deep neural network with attention model for scene text recognition

摘要

The authors present a deep neural network (DNN) with attention model for scene text recognition. The proposed model does not require any segmentation of the input text image. The framework is inspired by the attention model presented recently for speech recognition and image captioning. In the proposed framework, feature extraction, feature attention and sequence recognition are integrated in a jointly trainable network. Compared with previous approaches, the following contributions are mainly made. (i) The attention model is applied into DNN to recognise scene text, and it can effectively solve the sequence recognition problem caused by variable length labels. (ii) Rigorous experiments are performed across a number of challenging benchmarks, including IIIT5K, SVT, ICDAR2003 and ICDAR2013 datasets. Results in experiments show that the proposed model is comparable or better than the state-of-the-art methods. (iii) This model only contains 6.5 million parameters. Compared with other DNN models for scene text recognition, this model has the least number of parameters so far.
