GridFormer: Towards Accurate Table Structure Recognition via Grid Prediction

no code implementations26 Sep 2023 Pengyuan Lyu, Weihong Ma, Hongyi Wang, Yuechen Yu, Chengquan Zhang, Kun Yao, Yang Xue, Jingdong Wang

In this representation, the vertexes and edges of the grid store the localization and adjacency information of the table.

Recognition of Handwritten Chinese Text by Segmentation: A Segment-annotation-free Approach

no code implementations29 Jul 2022 Dezhi Peng, Lianwen Jin, Weihong Ma, Canyu Xie, Hesuo Zhang, Shenggao Zhu, Jing Li

A novel weakly supervised learning method is proposed to enable the network to be trained using only transcript annotations; thus, the expensive character segmentation annotations required by previous segmentation-based methods can be avoided.

Towards an efficient framework for Data Extraction from Chart Images

no code implementations5 May 2021 Weihong Ma, Hesuo Zhang, Shuang Yan, Guangshun Yao, Yichao Huang, Hui Li, Yaqiang Wu, Lianwen Jin

For building a robust point detector, a fully convolutional network with feature fusion module is adopted, which can distinguish close points compared to traditional methods.

Joint Layout Analysis, Character Detection and Recognition for Historical Document Digitization

1 code implementation14 Jul 2020 Weihong Ma, Hesuo Zhang, Lianwen Jin, Sihang Wu, Jiapeng Wang, Yongpan Wang

In this framework, two branches named character branch and layout branch are added behind the feature extraction network.
