Abstract:

The text detection and recognition technology is introduced in this paper. Firstly, the research background, application fields and technical difficulties of the natural scene character recognition technology are introduced. Secondly, the preprocessing technology and process of scene text recognition are introduced. Then it introduces the universal deep learning detection network based on deep learning, deep learning text detection network based on Uyghur and Chinese and English, deep learning network based on scene character recognition, end to end scene character detection and recognition deep learning network, this paper summarizes the structure features, advantages, limitations, application scenarios and implementation costs of various networks, and then makes a comprehensive analysis. Finally, it introduces the open data sets, the development trend and possible research direction of scene character recognition technology are also discussed.

Key words: scene text detection, text recognition, deep learning, end-to-end detection and recognition
