## Online Application ()

A **Single** model! Only **7M**! Process **2K** resolution image with a **Fast** speed on common PCs or Mobiles! **Beter** than research demos!  
Please try online portrait image matting via [this website](https://sight-x.cn/portrait_matting) or on [my personal homepage](https://zhke.io/#/?modnet_demo)!

## Research Demo

All the models behind the following demos are trained on the datasets mentioned in [our paper](https://arxiv.org/pdf/2011.11961.pdf).

### Portrait Image Matting
We provide an [online Colab demo](https://colab.research.google.com/drive/1GANpbKT06aEFiW-Ssx0DQnnEADcXwQG6?usp=sharing) for portrait image matting.  
It allows you to upload portrait images and predict/visualize/download the alpha mattes.



### Portrait Video Matting
We provide two real-time portrait video matting demos based on WebCam. When using the demo, you can move the WebCam around at will.
If you have an Ubuntu system, we recommend you to try the [offline demo](demo/video_matting/webcam) to get a higher *fps*. Otherwise, you can access the [online Colab demo](https://colab.research.google.com/drive/1Pt3KDSc2q7WxFvekCnCLD8P0gBEbxm6J?usp=sharing).  
We also provide an [offline demo](demo/video_matting/custom) that allows you to process custom videos.




## Community

We share some cool applications/extentions of MODNet built by the community.

- **WebGUI for Portrait Image Matting**  
You can try [this WebGUI](https://www.gradio.app/hub/aliabd/modnet) (hosted on [Gradio](https://www.gradio.app/)) for portrait image matting from your browser without code!

- **Colab Demo of Bokeh (Blur Background)**  
You can try [this Colab demo](https://colab.research.google.com/github/eyaler/avatars4all/blob/master/yarok.ipynb) (built by [@eyaler](https://github.com/eyaler)) to blur the backgroud based on MODNet!

- **ONNX Version of MODNet**  
You can convert the pre-trained MODNet to an ONNX model by using [this code](onnx) (provided by [@manthan3C273](https://github.com/manthan3C273)). You can also try [this Colab demo](https://colab.research.google.com/drive/1P3cWtg8fnmu9karZHYDAtmm1vj1rgA-f?usp=sharing) for MODNet image matting (ONNX version).

- **TorchScript Version of MODNet**  
You can convert the pre-trained MODNet to an TorchScript model by using [this code](torchscript) (provided by [@yarkable](https://github.com/yarkable)).

- **TensorRT Version of MODNet**  
You can access [this Github repository](https://github.com/jkjung-avt/tensorrt_demos) to try the TensorRT version of MODNet (provided by [@jkjung-avt](https://github.com/jkjung-avt)).

- **Docker Container for MODnet**  
You can access [this Github repository](https://github.com/nahidalam/modnet_docker) for a containerized version of MODNet with the Docker environment (provided by [@nahidalam](https://github.com/nahidalam)).


There are some resources about MODNet from the community.

- [Article from Louis Bouchard's Blog](https://www.louisbouchard.ai/remove-background/)


## Code
We provide the [code](src/trainer.py) of MODNet training iteration, including:
- **Supervised Training**: Train MODNet on a labeled matting dataset
- **SOC Adaptation**: Adapt a trained MODNet to an unlabeled dataset

In code comments, we provide examples for using the functions.  


## PPM Benchmark
The PPM benchmark is released in a separate repository [PPM](https://github.com/ZHKKKe/PPM).
