PingAn-VCGroup's Solution for ICDAR 2021 Competition on Scientific Table Image Recognition to Latex

Recognizing a table image into a Latex code is challenging due to complexity and diversity of table structures and long sequence problem compared to traditional OCR. The challenge aims at assessing the ability of state-of-the-art methods to recognize scientific tables into LaTeX codes. In this competition, there are two sub-tasks with different levels of difficulty. Subtask I Table Structure Reconstruction is to reconstruct the structure of a table image into the form of LaTeX code but ignore the content of the table. Subtask II Table Content Reconstruction is to reconstruct the structure and the content of a table image simultaneously into the form of LaTeX code.
