| # UIKA |
|
|
| This repository hosts the released model weights and auxiliary assets for **UIKA: Fast Universal Head Avatar from Pose-Free Images**. |
|
|
| UIKA is a feed-forward model for creating animatable 3D Gaussian head avatars from pose-free inputs. It supports a single reference image, multiple images of the same identity, or smartphone-style video captures. Use these files together with the official PyTorch code: |

| ## Files |
|
|
| - `uika.safetensors` - main UIKA checkpoint. The official inference config expects it at `model_zoo/uika/uika.safetensors`. |
| - `fuvt_15k.safetensors` - FUVT UV-estimation module checkpoint used by UIKA. |
| - `human_parametric_models.tar` - human parametric model assets required by the pipeline. Third-party assets may have separate license terms. |
| - `ref_motion_example.tar` - example reference/motion assets for testing inference. |
