# SkeletonDiffusion: Nonisotropic Gaussian Diffusion for Realistic 3D Human Motion Prediction
|
| 10 |
+
This is the official Huggingface space of the CVPR2025 paper _Nonisotropic Gaussian Diffusion for Realistic 3D Human Motion Prediction_, codebase available [here](https://github.com/Ceveloper/SkeletonDiffusion/tree/main).
|
| 11 |
+
|
| 12 |
+
SkeletonDiffusion is a probabilistic human motion prediction model that takes as input 0.5s of human motion and generates future motions of 2s with a inference time of 0.4s.
|
| 13 |
+
SkeletonDiffusion generates motions that are at the same time realistic and diverse. It is a latent diffusion model that with a custom graph attention architecture trained with a nonisotropic Gaussian diffusion formulation reflecting body joint connections.
|
| 14 |
+
|
| 15 |
+
We provide a model for each dataset mentioned in the paper (AMASS, FreeMan, Human3.6M), and a further model trained on AMASS with hands joints (AMASS-MANO).

## Online demo
|
| 21 |
+
The model trained on AMASS is accessible in a demo workflow that predicts future motions from videos.
|
| 22 |
+
The demo extracts 3D human poses from video via Neural Localizer Fields ([NLF](https://istvansarandi.com/nlf/)) by Sarandi et al., and SkeletonDiffusion generates future motions conditioned on the extracted poses:
|
| 23 |
+
SkeletonDiffusion has not been trained with real-world, noisy data, but despite this fact it can handle most cases reasonably.
