GDB: Gated convolutions-based Document Binarization

1 code implementation4 Feb 2023 Zongyuan Yang, Yongping Xiong, Guibin Wu

However, existing methods can not extract stroke edges finely, mainly due to the fair-treatment nature of vanilla convolutions and the extraction of stroke edges without adequate supervision by boundary-related information.

Transmission Dynamics of COVID-19 Pandemic Non-pharmaceutical Interventions and Vaccination

no code implementations7 Jul 2021 Bin-Guo Wang, Shunxiang Huang, Yongping Xiong, Ming-Zhen Xin, Jing Li, Jiangqian Zhang, Zhihui Ma

By simulating the relation ships of the basic reproduction number $\mathscr{R}_{0}$, the vaccination rate and the efficiency of vaccine, we find that it is impossible to achieve the herd immunity without NPIs when the efficiency of vaccine is lower than $76. 9\%$.
