# HGGT: Robust and Flexible 3D Hand Mesh Reconstruction from Uncalibrated Images

We introduce **Hand Geometry Grounding Transformer (HGGT)**, a scalable and generalized solution for **3D hand mesh recovery**. Our method unifies diverse data sources to achieve robust performance across varying camera viewpoints and environments.

This repository provides the **model weights** for **HGGT**, introduced in:
