# MILL3D Benchmark Protocol

MILL3D is designed for controlled benchmarking across scenes and exposure levels.

## Pairing Rule

For a given scene, images with the same `image_name` across different `level_name` folders are paired captures of the same viewpoint.

## Reference Rule

For each low-light sample:
- input image: `data/{scene_name}/{level_name}/images/{image_name}`
- reference image: `data/{scene_name}/GT/images/{image_name}`

## Intended Evaluation Use

- Evaluate reconstruction quality exposure-by-exposure
- Compare robustness across low-light severity levels
- Report metrics consistently across scenes and levels

## Notes

This dataset is intended primarily for evaluation and benchmarking, rather than as a large-scale training corpus.
