UnReflectAnything

RGB-Only Highlight Removal by Rendering Synthetic Specular Supervision

UnReflectAnything inputs any RGB image and removes specular highlights, returning a clean diffuse-only output. We trained UnReflectAnything by synthetizing specularities and supervising in DINOv3 feature space.

UnReflectAnything works on both natural indoor and surgical/endoscopic domain data.

[!IMPORTANT] The maintainers are still working on an official API and Weights release for UnReflectAnything. In v1.0.2 the model is available from the API with pretrained=False by deafault, and forecefully setting it True will display a warning and weights will not be downloaded. Stay tuned for the official release!

Installation

pip install unreflectanything

Install UnReflectAnything as a Python Package.

The minimum required Python version is 3.11, but development and all experiments have been based on Python 3.12.

For GPU support, make sure PyTorch comes with CUDA version for your system (see PyTorch Get Started).

Setting up

After pip-installing, you can use the unreflectanything CLI command, which is also aliased to unreflect and ura. The three commands are equivalent.

With the CLI you can already download the model weights with

unreflectanything download --weights

and some sample images with

unreflectanything download --images

Weights are stored by default in ~/.cache/unreflectanything/weights (or $XDG_CACHE_HOME/unreflectanything/weights if set ; %LOCALAPPDATA%\unreflectanything for Windows). Use --output-dir to choose another location.

Both the weights and images are stored on the HuggingFace Model Repo.

Enable shell completion

Shell completion is available for the bash and zsh shells. Run

unreflectanything completion bash

and execute the echo ... command that gets printed.

Command Line Interface

Get an overview of the available CLI endpoints with

unreflectanything --help   # alias 'unreflect --help' alias 'ura --help'

Refer to the Wiki to get detailed documentation about each endpoint. We report a summary of the available subcommands. Remember that ura is aliased to the unreflectanything command

Training, testing, and evaluation are available via the Python API; see the Wiki for details.

Python API

The same endpoints above are exposed as a Python API. Refer to the Wiki to get detailed documentation about each endpoint. A few examples are reported below

import unreflectanything as unreflect
import torch

# Get the model class (e.g. for custom setup or training)
ModelClass = unreflect.model()

# Get a pretrained model (torch.nn.Module) and run on batched RGB
unreflectmodel = unreflect.model(pretrained=True)  # uses cached weights; run 'unreflect download --weights' first
images = torch.rand(2, 3, 448, 448, device="cuda")  # [B, 3, H, W], values in [0, 1]
model_out = unreflectmodel(images)  # [B, 3, H, W] diffuse tensor

# File-based or tensor-based inference (one-shot, no model handle)
unreflect.inference("input.png", output="output.png")
unreflect.inference(images, output="output.png")
result = unreflect.inference(images)

# Cache directory (where weights, images, etc. are stored)
weights_dir = unreflect.cache("weights")

Contributing & Development

If you want to contribute or develop UnReflectAnything:

1. Clone the repository:

   git clone https://github.com/alberto-rota/UnReflectAnything.git
   cd UnReflectAnything
   

2. Install dependencies (we recommend a virtual environment with Python 3.12):

   pip install -r requirements.txt
