## What is in this Hub repository?

This **model** repo ships two top-level folders:

| Folder on Hub | Role |
|----------------|------|
| **`VITON-Extends_test/`** | Code and assets to run **inference / demo** (`test.py`, networks, options, etc.). |
| **`VITON-Extends-Train/`** | **Training-side** bundle (scripts, configs, or checkpoints—whatever you packaged locally under that directory). |

Download the full repo (or a subset with `allow_patterns`) and point your local paths to these folders as in the [GitHub README](https://github.com/nguyendinhhieu1309/VITON-Extends).

**Dataset (images)** is hosted separately: **[NguyenDinhHieu/VITON-Extends-DB](https://huggingface.co/datasets/NguyenDinhHieu/VITON-Extends-DB)** (see that dataset card for `Train.zip` / `Test.zip` and extraction).

## Abstract

Garment fitting in virtual try-on often fails under **complex poses**, **occlusions**, and **misalignment** between person and garment. VITON-Extends improves **pose adaptability** and **garment warping** with a **global appearance flow** model, **StyleGAN-style** global modulation, and a **local flow refinement** stage. On the VITON benchmark, results are strong especially in challenging poses.

## Quick download (Python)

```python
from huggingface_hub import snapshot_download

path = snapshot_download(
    repo_id="NguyenDinhHieu/VITON-Extends",
    local_dir="./VITON-Extends_hf",
)
# Then use ./VITON-Extends_hf/VITON-Extends_test/ and ./VITON-Extends_hf/VITON-Extends-Train/
```

## Environment (reference)

Versions below match the **paper / reference** setup; your local `VITON-Extends_*` trees may ship their own `requirements.txt`—prefer those for exact pins.

| Component | Reference version |
|-----------|-------------------|
| PyTorch | 2.2.1+cu118 (example) |
| TorchVision | 0.17.1+cu118 |
| CuPy | 13.3.0 |
| OpenCV | 4.10.0 |
| Python | 3.12 (or as in project env) |

## Training & testing (outline)

1. **Data:** Use **[VITON-Extends-DB](https://huggingface.co/datasets/NguyenDinhHieu/VITON-Extends-DB)** — unzip `Train.zip` / `Test.zip`, set `dataroot` to `train/` or `test/` as in the dataset card.
2. **Checkpoints:** Place warping / generation weights where the GitHub repo expects (e.g. under `checkpoints/VITON-Extends/`).
3. **Train:** Run the shell scripts under `scripts/` from the GitHub repository (parser-based then parser-free stages).
4. **Test:** From the downloaded **`VITON-Extends_test/`** tree, follow repo instructions, e.g.  
   `python test.py --name demo --resize_or_crop None --batchSize 1 --gpu_ids 0`

For **FID** and extra assets, see links in the [GitHub README](https://github.com/nguyendinhhieu1309/VITON-Extends).
