MODNet is a trimap-free model for portrait matting in real time under changing scenes.
--- ## News - [Dec 10 2020] Release [Video Matting Demo](https://colab.research.google.com/drive/1Pt3KDSc2q7WxFvekCnCLD8P0gBEbxm6J?usp=sharing) and [Image Matting Demo](https://colab.research.google.com/drive/1GANpbKT06aEFiW-Ssx0DQnnEADcXwQG6?usp=sharing). - [Nov 24 2020] Release [Arxiv Preprint](https://arxiv.org/pdf/2011.11961.pdf) and [Supplementary Video](https://youtu.be/PqJ3BRHX3Lc). ## Video Matting Demo 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). ## Image Matting Demo 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. ## TO DO - Release training code (scheduled in **Jan. 2021**) - Release PPM-100 validation benchmark (scheduled in **Feb. 2021**) ## License This project is released under the [Creative Commons Attribution NonCommercial ShareAlike 4.0](https://creativecommons.org/licenses/by-nc-sa/4.0/legalcode) license. ## Acknowledgement We thank [City University of Hong Kong](https://www.cityu.edu.hk/) and [SenseTime](https://www.sensetime.com/) for their support to this project. ## Citation If this work helps your research, please consider to cite: ```bibtex @article{MODNet, author = {Zhanghan Ke and Kaican Li and Yurou Zhou and Qiuhua Wu and Xiangyu Mao and Qiong Yan and Rynson W.H.
