+# Card Calibration Dataset (v1)
+
+255 hand-collected photos of color calibration cards, with augmentations,
+YOLO annotations, and extracted feature crops.
+
+Used to train [`jeffliulab/card-calibration-v1`](https://huggingface.co/jeffliulab/card-calibration-v1).
+Live demo: [`jeffliulab/card-calibration-v1` Space](https://huggingface.co/spaces/jeffliulab/card-calibration-v1).
+
+## Contents
+
+| Archive | Files | Description |
+|---|---|---|
+| `raw_photos.tar.gz` | 255 | Original hand-collected photos |
+| `augmented_images.tar.gz` | 2,294 | Albumentations-augmented variants (brightness/hue/blur/etc) |
+| `feature_crops.tar.gz` | 9,154 | Center-region patch crops (4 patches × ~2,294 images) |
+| `yolo_card_dataset.tar.gz` | 510 | YOLO stage-1 training set (card detection) |
+| `yolo_pattern_dataset.tar.gz` | 510 | YOLO stage-2 training set (pattern detection) |
+| `yolo_labeled_card.tar.gz` | 510 | Raw YOLO annotations (stage 1) |
+| `yolo_labeled_patterns.tar.gz` | 510 | Raw YOLO annotations (stage 2) |
+| `generalization_test.png` | 1 | Held-out generalization test photo |
+| `features/feature_0216.csv` | 1 | Final training feature CSV (12-D + target) |
+| `features/GridMean_0216.csv` | 1 | Intermediate grid mean values |
+| `features/unique_colors.csv` | 1 | Unique color reference values |
+
+## Usage
+
+The companion repo provides a one-command download script:
+
+```bash
+git clone https://github.com/jeffliulab/Color_Calibration.git
+cd Color_Calibration
+python scripts/dataset_download.py
+```
+
+This downloads all archives and extracts them into `data/` matching the layout
+expected by the training scripts in `src/`.
+
+## Manual download
+
+```python
+from huggingface_hub import snapshot_download
+snapshot_download(
+    repo_id="jeffliulab/card-calibration-v1-data",
+    repo_type="dataset",
+    local_dir="./dataset_cache",
+)
+```
+
+## Known issues
+
+6 augmented feature crop files are missing (gsutil transfer failures during
+the migration from GCS). These are non-critical center-region crops and do not
+affect training or evaluation.
+
+## License
+
+MIT — both data and code are freely available for research and commercial use.
