Benchmarking Chinese Text Recognition: Datasets, Baselines, and an Empirical Study

1 code implementation30 Dec 2021 Jingye Chen, Haiyang Yu, jianqi ma, Mengnan Guan, Xixi Xu, Xiaocong Wang, Shaobo Qu, Bin Li, xiangyang xue

Based on our observations, we attribute the scarce attention on Chinese text recognition to the lack of reasonable dataset construction standards, unified evaluation methods, and results of the existing baselines.

Text Prior Guided Scene Text Image Super-resolution

1 code implementation29 Jun 2021 jianqi ma, Shi Guo, Lei Zhang

Our experiments on the benchmark TextZoom dataset show that TPGSR can not only effectively improve the visual quality of scene text images, but also significantly improve the text recognition accuracy over existing STISR methods.

RRPN++: Guidance Towards More Accurate Scene Text Detection

1 code implementation28 Sep 2020 Jianqi Ma

In inference stage, the detection branch outputs the proposal refinement and the recognition branch predicts the transcript of the refined text region.

Multi-Task Learning Scene Text Detection
