# Hugging Face Integration - Summary

## Overview

Your **WearIT Garment Mask** project has been successfully transformed into a Hugging Face-compatible model! This document summarizes all the changes and new files created.

## 📦 New Files Created

### 1. `pipeline.py` - Hugging Face Pipeline Wrapper
**Purpose**: Wraps your `GarmentMaskProcessor` in a standard Hugging Face `Pipeline` class.

**Key Features**:
- ✅ Inherits from `transformers.Pipeline`
- ✅ Implements required methods: `_sanitize_parameters()`, `preprocess()`, `_forward()`, `postprocess()`
- ✅ Compatible with `pipeline()` function from transformers
- ✅ Handles both local paths and HF Hub model loading
- ✅ Fallback support (works without transformers installed)

**Usage**:
```python
from transformers import pipeline
pipe = pipeline("image-segmentation", model="your-username/wearit-garment-mask", trust_remote_code=True)
results = pipe("image.jpg", garment_types="upper")
```

### 2. `config.json` - Model Configuration
**Purpose**: Stores all default parameters and model metadata.

**Contains**:

4. Custom configuration
5. Using PIL Images
6. Integration with inpainting models

### 5. `.gitignore` - Version Control
**Purpose**: Excludes temporary files and outputs from git.

**Ignores**:
- Python cache files
- Output directories
- Temporary files
- Virtual environments
- IDE files

### 6. `LICENSE` - Apache 2.0 License
**Purpose**: Legal protection and open-source compliance.

**Includes**:

### 7. `HF_HUB_UPLOAD_GUIDE.md` - Upload Instructions
**Purpose**: Step-by-step guide for uploading to Hugging Face Hub.

**Covers**:
- Prerequisites and setup
- Two upload methods (Python API and Git)
- Handling large checkpoint files
- Testing uploaded model
- Best practices
- Creating a Gradio demo

### 8. `requierments.txt` - Updated Dependencies
**Purpose**: Lists all required Python packages.

**Additions**:
- `transformers>=4.36.0` - For Pipeline support
- `huggingface_hub>=0.19.0` - For HF Hub integration
- `matplotlib>=3.5.0` - For visualization examples
- `diffusers` - Optional, for inpainting demo

## 🚀 How to Use Your New HF Model

### Option 1: Local Usage (Without Upload)

```python
# Direct import
from pipeline import GarmentMaskPipeline

pipe = GarmentMaskPipeline(device="cuda:0")
results = pipe("image.jpg", garment_types="upper")
```

### Option 2: After Uploading to HF Hub

```python
# Load from Hugging Face Hub
from transformers import pipeline

pipe = pipeline(
    "image-segmentation",
    model="your-username/wearit-garment-mask",
    trust_remote_code=True
)
results = pipe("image.jpg", garment_types=["upper", "lower"])
```

## 📤 Next Steps: Upload to Hugging Face Hub

Follow these steps to publish your model:

### Step 1: Install HF CLI
```bash
pip install huggingface_hub
huggingface-cli login
```

### Step 2: Create Repository
```python
from huggingface_hub import create_repo
create_repo("wearit-garment-mask", repo_type="model")
```

### Step 3: Upload Files
```python
from huggingface_hub import upload_folder
upload_folder(
    folder_path=".",
    repo_id="your-username/wearit-garment-mask",
    repo_type="model"
)
```

### Step 4: Test
```python
from transformers import pipeline
pipe = pipeline("image-segmentation", model="your-username/wearit-garment-mask", trust_remote_code=True)
```

**Full details**: See `HF_HUB_UPLOAD_GUIDE.md`

## ⚙️ Configuration Options

Your pipeline now supports extensive configuration:

```python
pipe = GarmentMaskPipeline(
    device="cuda:0",                      # Device selection
    output_height=1024,                   # Output resolution
    process_size=512,                     # Processing size
    use_convex_hull=True,                 # Convex hull smoothing
    schp_batch_size=12,                   # SCHP batch size
    allowed_strategies=["ellipse", "box"], # Mask strategies
    save_images=False                     # Save intermediate results
