# STGCN
## Introduction
STGCN is one of the first algorithms that adopt Graph Convolution Neural Networks for skeleton processing. We provide STGCN trained on NTURGB+D with 2D skeletons (HRNet) and 3D skeletons in both the original training setting and the **PYSKL** training setting. We provide checkpoints for four modalities: Joint, Bone, Joint Motion, and Bone Motion. The accuracy of each modality links to the weight file.

## Model Zoo
We release numerous checkpoints trained with various modalities, annotations on NTURGB+D and NTURGB+D 120. The accuracy of each modality links to the weight file.
