## 🔍 About SDMatte

**SDMatte: Grafting Diffusion Models for Interactive Matting** is a state-of-the-art model that leverages the power of **diffusion priors** to achieve high-precision matting — especially around fine details and complex edges.

### ✨ Key Features

- **Diffusion-Powered**: Uses strong priors from diffusion models to extract high-fidelity details  
- **Interactive Matting**: Visual prompt-driven control for intuitive editing  
- **Edge & Texture Focus**: Excels in handling challenging edge regions and fine textures  
- **Coordinate & Opacity Awareness**: Improves matting accuracy with spatial and opacity context  

---

## 📦 Available Models

- `SDMatte.safetensors` – Standard version for interactive matting  
- `SDMatte_plus.safetensors` – Enhanced version with improved performance

### 📝 Abstract (from the original paper)

> Recent interactive matting methods have shown satisfactory performance in capturing the primary regions of objects, but they fall short in extracting fine-grained details in edge regions. Diffusion models trained on billions of image-text pairs demonstrate exceptional capability in modeling highly complex data distributions and synthesizing realistic texture details, while exhibiting robust text-driven interaction capabilities — making them an attractive solution for interactive matting.
