# PST50: Benchmark for Photorealistic Style Transfer
**PST50** is the first benchmark dataset designed for rigorous evaluation of **Photorealistic Style Transfer (PST)**. It includes high-resolution, professionally curated content-style pairs with ground truth stylizations, suitable for both **paired** and **unpaired** evaluation protocols.
This dataset is introduced in the paper:
**SA-LUT: Spatial Adaptive 4D Look-Up Table for Photorealistic Style Transfer**

## 📁 Dataset Structure
```bash
PST50/
├── video/ # Content videos in log color space
├── content_709/ # Content images in Rec.709 color space
├── content_log/ # Content image in log color space
├── paired_gt/ # Ground truth stylized outputs for paired evaluation
├── paired style/ # Style references for paired evaluation
└── unpaired_style/ # Style references for unpaired evaluation
```
## 🧪 Evaluation Protocol
- Paired: Compare stylized outputs against `paired_gt` using metrics like LPIPS, PSNR, SSIM, and H-Corr.
- Unpaired: Use `unpaired_style` with stylized outputs for qualitative or perceptual studies.
- Video: Apply models to video sequences to test temporal consistency and real-time stylization.
