This model card is for the `gsfixer-base` model, which is designed for novel view repair of an image rendered from a 3DGS model. The model is fine-tuned from the `stable-diffusion-2` [model](https://huggingface.co/stabilityai/stable-diffusion-2) following [Marigold](https://github.com/prs-eth/Marigold/tree/main) protocol. 

#### Other Versions

* [gsfixer-full](https://huggingface.co/goldoak1421/gsfixer-full): A version of this model that operates on both mesh and 3DGS input.


## Model Details
- **Developed by:** Jiaxin Wei, Stefan Leutenegger, Simon Schaefer.
- **License:** [CreativeML Open RAIL++-M License](https://github.com/GSFix3D/GSFix3D/blob/main/LICENSES/LICENSE-MODEL.txt).
- **Model Description:** This model can be used to generate a repaired image of an input rendered image. 
  - **Resolution**: Even though any resolution can be processed, the model inherits the base diffusion model's effective resolution of roughly **768** pixels. 
    This means that for optimal predictions, any larger input image should be resized to make the longer side 768 pixels before feeding it into the model.
  - **Steps and scheduler**: This model was designed for usage with the **DDIM** scheduler and between **1 and 50** denoising steps.
