# [WACV'26] Low-light Smartphone Dataset (LSD)

This is the official dataset proposed in our paper titled **"Illuminating Darkness: Learning to Enhance Low-light Images In-the-Wild"**

📄 **Paper:** [arXiv](https://arxiv.org/abs/2503.06898)  
💻 **Code:** [GitHub - LSD-TFFormer](https://github.com/sharif-apu/LSD-TFFormer)

## Overview

We introduce **LSD**, the largest in-the-wild Single-Shot Low-Light Image Enhancement (SLLIE) dataset to date.

## Dataset Structure

This repository contains the following training data files:

- `patch_DLL_gtPatch.tar.gz`
- `patch_DLL_inputPatch.tar.gz`
- `patch_NLL_gtPatch.tar.gz`
- `patch_NLL_inputPatch.tar.gz`

### Categories

- **DLL (Denoised Low-Light):** For low-light enhancement training
- **NLL (Noisy Low-Light):** For joint denoising + enhancement training

### File Organization

- `inputPatch`: Low-light input images
- `gtPatch`: Ground truth (well-lit) reference images

## Usage

Extract the archives to access the training patches:

```bash
tar -xzf patch_DLL_gtPatch.tar.gz
tar -xzf patch_DLL_inputPatch.tar.gz
tar -xzf patch_NLL_gtPatch.tar.gz
tar -xzf patch_NLL_inputPatch.tar.gz
```

## Dataset Status

✅ **Training Dataset:** Available (current files)  
🔄 **Test Dataset:** Coming soon
