Embodiment Construction
[0033] In order to make the technical solution of the present invention more comprehensible, specific embodiments and accompanying drawings are described in detail as follows.
[0034] This embodiment proposes a scene character recognition method (SE-ASTER for short) based on the semantically enhanced encoder-decoder framework, based on the semantically enhanced encoder-decoder structure (SEED), such as figure 1 As shown, in the existing framework, SEED uses the visual information output by the encoder to predict a global semantic information, and introduces the word vector commonly used in the field of natural language processing as a supervision of it, and then uses this global semantic information information to guide the subsequent decoding process. At the same time, a new mainstream method ASTER is combined with the proposed framework, and a new scene image text recognition method SE-ASTER is proposed. Such as figure 2 As shown, SE-ASTER is implemented by a scene text ...
