Attention Guidance Mechanism for Handwritten Mathematical Expression Recognition

no code implementations • 4 Mar 2024 • Yutian Liu, Wenjun Ke, Jianguo Wei

Handwritten mathematical expression recognition (HMER) is challenging in image-to-text tasks due to the complex layouts of mathematical expressions and suffers from problems including over-parsing and under-parsing.

Omni Aggregation Networks for Lightweight Image Super-Resolution
