Self-Attention Based Text Knowledge Mining for Text Detection

1 code implementation • CVPR 2021 • Qi Wan, Haoqin Ji, Linlin Shen

Considering the importance of exploring text contents for text detection, we propose STKM (Self-attention based Text Knowledge Mining), which consists of a CNN Encoder and a Self-attention Decoder, to learn general prior knowledge for text detection from SynthText.
