Reading Chinese in Natural Scenes with a Bag-of-Radicals Prior. (arXiv:2210.02576v1 [cs.CV])

Scene text recognition (STR) on Latin datasets has been extensively studied
in recent years, and state-of-the-art (SOTA) models often reach high accuracy.
However, the performance on non-Latin transcripts, such as Chinese, is not
satisfactory. In this paper, we collect six open-source Chinese STR datasets
and evaluate a series of classic methods performing well on Latin datasets,
finding a significant performance drop. To improve the performance on Chinese
datasets, we propose a novel radical-embedding (RE) representation to utilize
the ideographic descriptions …
