SLANet-1M: A Lightweight Model for Table Recognition

---

🧾 Overview

SLANet-1M is a lightweight convolutional model for table recognition designed to extract table structure and cell content from document images efficiently.
It is trained on over one million synthetic and real-world tables and provides competitive performance compared to transformer-based architectures—while being significantly smaller and faster.

This model was developed as part of a Master’s thesis at the University of Florence and the Swiss AI Center (iCoSys, Fribourg), and presented at SwissText 2025.

The paper is available here.
