Benchmark evaluation workspace for the **DiffCR** paper
(*Diffusion-Based Cloud Removal for Sentinel-2 Multi-Temporal Imagery*).
Two test datasets are covered:
| Dataset | Samples | Methods |
|---|---|---|
| Sen2\_MTC\_Old | 313 | 12 |
| Sen2\_MTC\_New | 687 | 12 |

## Quick Start
### 1. Install dependencies
```bash
pip install -r eval/requirements.txt
```
> **CUDA note** – SSIM uses the 3-D Gaussian kernel from the paper, which
> requires a CUDA-enabled PyTorch installation to reproduce the exact paper
> values. PSNR, FID and LPIPS are fully reproducible on CPU.
> Install the correct torch wheel for your GPU from https://pytorch.org.

### 2. Run evaluation
```bash
# Evaluate all 12 methods on both datasets (prints a full summary table):
python eval/metrics.py
# One specific method:
python eval/metrics.py --method diffcr
# One specific dataset:
python eval/metrics.py --dataset Sen2_MTC_New
# One method + one dataset:
python eval/metrics.py --dataset Sen2_MTC_Old --method diffcr
# Fast check (skip FID and LPIPS):
python eval/metrics.py --no-fid --no-lpips
# Arbitrary directory pair:
python eval/metrics.py --gt /path/to/GT --pred /path/to/Out
```
Expected output (excerpt, requires CUDA for exact SSIM):
```
Method | Sen2_MTC Old | Sen2_MTC New
| PSNR SSIM FID LPIPS | PSNR SSIM FID LPIPS
--------------------------------------------------------------------------------
...
diffcr | 29.112 0.886 89.845 0.258 | 19.150 0.671 83.162 0.291
```
---
### 3. Generate comparison figures
```bash
# Generate the exact figures used in the paper:
python eval/plot.py --paper-samples
# Paper figures for one dataset:
python eval/plot.py --paper-samples --dataset Sen2_MTC_New
python eval/plot.py --paper-samples --dataset Sen2_MTC_Old
# Any specific sample:
python eval/plot.py --dataset Sen2_MTC_New --id T12TUR_R027_55
# List all available sample IDs:
python eval/plot.py --dataset Sen2_MTC_New --list
# Generate figures for every sample:
python eval/plot.py --dataset Sen2_MTC_New --all
```
Figures are saved as PDF to `eval/plots/` by default.

## Notes
- All images use the unified naming scheme `{id}.png` (GT and predictions)
and `{id}_A{1,2,3}.png` (cloudy inputs).
- `results/Sen2_MTC_Old/diffcr/` images are stored in their original
coordinate convention; `eval/plot.py` applies a horizontal flip
automatically when rendering the Old-dataset comparison figure so that
all panels share a consistent visual orientation.
- `migrate.py` in the project root was the one-time script used to produce
the current layout from the original raw experiment directories.
It is kept for reference but does not need to be re-run. |
