# U²-Net Segmentation Models

Backup mirror of segmentation models used by [rembg](https://github.com/danielgatis/rembg) for background removal, hosted by [AEmotionStudio](https://github.com/AEmotionStudio) for use with [ComfyUI-FFMPEGA](https://github.com/AEmotionStudio/ComfyUI-FFMPEGA).

## Status

> ⚠️ **Models pending upload.** The repo has been created but model files have not been uploaded yet. The background removal skill in FFMPEGA is under active development.

## Planned Models

| Model | Format | Use Case |
|:------|:-------|:---------|
| `u2net.onnx` | ONNX | General-purpose segmentation |
| `silueta.onnx` | ONNX | Lightweight silhouette detection |
| `isnet-general-use.onnx` | ONNX | High-quality general segmentation |

**Original source:** [danielgatis/rembg](https://github.com/danielgatis/rembg)

## Why This Mirror?

This is a defensive backup maintained by AEmotionStudio to ensure supply chain resilience for the background removal feature once it is fully implemented.
