# Sintel Low-light Noise ELD

A synthetic low-light optical flow dataset derived from MPI Sintel using the ELD low-light noise preset.

This dataset contains noisy RGB frames for both the train and test splits and is intended for:

• —optical flow robustness evaluation in low-light conditions
• —fine-tuning pretrained optical flow models
• —controlled experiments on synthetic low-light degradation

## Contents

The dataset contains ELD-corrupted Sintel frames for:

• —training
• —test

This dataset includes only the noisy ELD data.

## What This Dataset Is For

This dataset is useful when you want to test or train optical flow models on darker, noisier Sintel-style inputs without changing the underlying scene content.

Typical use cases:

• —compare model performance on standard vs low-light inputs
• —fine-tune a pretrained model for low-light robustness
• —benchmark robustness under synthetic low-light degradation

## Noise Model

This dataset uses the ELD low-light noise model.

The ELD corruption includes:

• —brightness reduction
• —shot noise
• —read noise
• —quantization noise
• —banding artifacts

Compared with more aggressive synthetic corruption models, ELD generally produces more stable and visually plausible low-light results.

## Why Sintel + ELD?

MPI Sintel is widely used for optical flow evaluation, but it does not natively include low-light variants.

Applying ELD-style degradation provides:

• —a controlled robustness benchmark
• —the same scene/layout content as Sintel
• —a direct way to study low-light failure modes in optical flow

## Recommended Use

Best use:

• —fine-tune a pretrained optical flow model
• —evaluate robustness to low-light corruption
• —compare against clean Sintel performance

Less recommended:

• —treating this as real-world low-light ground truth
• —relying on it as the only low-light training source

This dataset is synthetic and is best used for controlled experiments.

## Notes

• —This dataset contains only the ELD noisy version.
• —It is a synthetic low-light corruption dataset, not a real capture dataset.
• —Transfer to real low-light video should be validated separately.
