GAS: Generative Avatar Synthesis from a Single Image

ICCV 2025

Project Page | Paper

Code release plan

• Inference code for novel view synthesis
• GAS checkpoints release on Hugging Face
• Inference code for novel pose synthesis
• Inference code for synchronized multi-view video generation

Requirements

• An NVIDIA GPU with CUDA support is required.
  • We have tested on a single A4500 and A100 GPU.
  • The minimum GPU memory required for inference is 20GB.
• Operating system: Linux

Installation

Instructions can be found in INSTALL.md.

Inference

Create a folder demo_images inside the project directory and move your testing image into it, e.g., GAS/demo_images/image.png.

Novel view synthesis

bash demo_scripts/nv.sh

Novel pose synthesis

TBD

Multi-view video generation

TBD
