GSFixer Full Model Card

Other Versions

• gsfixer-base: A version of this model that operates solely on 3DGS input.

Model Details

• Developed by: Jiaxin Wei, Stefan Leutenegger, Simon Schaefer.
• License: CreativeML Open RAIL++-M License.
• Model Description: This model can be used to generate a repaired image of two input rendered images from the mesh and 3DGS, respectively.
  • 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.
