| # Shuffle PatchMix (SPM) — Hugging Face Space | |
| An interactive demo for SPM augmentation. | |

| ## Parameters | |
| - **Grid (N×N):** Choose one of **2×2, 4×4, 8×8, 16×16**. The image is cropped (top-left) so its width and height are divisible by N. | |
| - **Enable Overlap Patch Blend):** When enabled, each base cell expands by ±overlap pixels (2× at borders to keep areas comparable) and patches are blended with a feather mask. | |
| - **Overlap (px):** Pixel overlap per side. Automatically clipped to `< 1/2 * patch size`. | |
| - **Mix probability:** Per-patch probability to mix original and a shuffled patch. | |
| - **Beta α, β:** Shape parameters for the Beta distribution used for blending weights. | |
| - **Seed:** Optional deterministic seed. | |
| ## Batch Mode | |
| Upload a `.zip` containing images (`.png`, `.jpg`, `.jpeg`). The app returns a `.zip` of augmented results with the same folder structure. | |
| ## Local Development | |
| ```bash | |
| pip install -r requirements.txt | |
| python app.py | |
| ``` | |
