Marigold Intrinsic Image Decomposition (IID) Lighting v1-1 Model Card

This is a model card for the marigold-iid-lighting-v1-1 model for single-image Intrinsic Image Decomposition (IID). The model is fine-tuned from the stable-diffusion-2 model as described in our papers:

• CVPR'2024 paper titled "Repurposing Diffusion-Based Image Generators for Monocular Depth Estimation"
• Journal extension titled "Marigold: Affordable Adaptation of Diffusion-Based Image Generators for Image Analysis"

Using the model

This model type (lighting) is trained to perform HyperSim decomposition into Albedo, Diffuse shading, and Non-diffuse residual. This decomposition aligns with the intrinsic residual model \(I = A*S+R\), where the image \(I\) is composed of a three-channel albedo \(A\), a three-channel diffuse shading component \(S\) (representing illumination color), and an additive three-channel residual term \(R\) capturing non-diffuse effects. The input is in the sRGB color space, while all outputs are in linear space. For an alternative model type (appearance) that performs decomposition into Albedo, Roughness, and Metallicity, click here.

Model Details

• Developed by: Bingxin Ke, Kevin Qu, Tianfu Wang, Nando Metzger, Shengyu Huang, Bo Li, Anton Obukhov, Konrad Schindler.
• Model type: Generative latent diffusion-based intrinsic image decomposition (lighting: albedo, diffuse shading, and non-diffuse residual) from a single image.
• Language: English.
• License: CreativeML Open RAIL++-M License.
• Model Description: This model can be used to generate an estimated intrinsic image decomposition of an input 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 DDIM scheduler and between 1 and 50 denoising steps.
  • Outputs:
    • Albedo: The predicted values are between 0 and 1, linear space.
    • Diffuse shading: The predicted values are between 0 and 1, linear space.
    • Non-diffuse residual: The predicted values are between 0 and 1, linear space.
    • Uncertainty maps: Produced for each modality only when multiple predictions are ensembled with ensemble size larger than 2.
