The model used in the online demo (unpublished) is only 7M!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 on my personal homepage for fun!

在线应用中使用的模型（未发布）大小仅为7M！可以在普通PC或移动设备上快速处理具有2K分辨率的图像！效果比研究示例更好！
请通过我的主页在线尝试图片抠像！

All the models behind the following demos are trained on the datasets mentioned in our paper.

We provide an online Colab demo for portrait image matting.
It allows you to upload portrait images and predict/visualize/download the alpha mattes.

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 to get a higher fps. Otherwise, you can access the online Colab demo.
We also provide an offline demo that allows you to process custom videos.

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

• Colab Demo of Bokeh (Blur Background)
  You can try this Colab demo (built by @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 (provided by @manthan3C273). You can also try this Colab demo 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 (provided by @yarkable).

• TensorRT Version of MODNet
  You can access this Github repository to try the TensorRT version of MODNet (provided by @jkjung-avt).

• Docker Container for MODnet
  You can access this Github repository for a containerized version of MODNet with the Docker environment (provided by @nahidalam).

There are some resources about MODNet from the community.

• Video from What's AI YouTube Channel
• Article from Louis Bouchard's Blog

We provide the code 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.

The PPM benchmark is released in a separate repository PPM.
