**EasyMocap** is an open-source toolbox for **markerless human motion capture** and **novel view synthesis** from RGB videos. In this project, we provide a lot of motion capture demos in different settings.
- :tada: Our SIGGRAPH 2022 [**Novel View Synthesis of Human Interactions From Sparse Multi-view Videos**](https://chingswy.github.io/easymocap-public-doc/works/multinb.html) is released! Check the [documentation](https://chingswy.github.io/easymocap-public-doc/works/multinb.html).
- :tada: EasyMocap v0.2 is released! We support motion capture from Internet videos. Please check the [Quick Start](https://chingswy.github.io/easymocap-public-doc/quickstart/quickstart.html) for more details.

This is the basic code for fitting SMPL[^loper2015]/SMPL+H[^romero2017]/SMPL-X[^pavlakos2019]/MANO[^romero2017] model to capture body+hand+face poses from multiple views.
With our proposed method, we release two large dataset of human motion: LightStage and Mirrored-Human. See the [website](https://chingswy.github.io/Dataset-Demo/) for more details.
If you would like to download the ZJU-Mocap dataset, please sign the [agreement](https://pengsida.net/project_page_assets/files/ZJU-MoCap_Agreement.pdf), and email it to Qing Shuai (s_q@zju.edu.cn) and cc Xiaowei Zhou (xwzhou@zju.edu.cn) to request the download link.
- Some functions are borrowed from [SPIN](https://github.com/nkolot/SPIN), [VIBE](https://github.com/mkocabas/VIBE), [SMPLify-X](https://github.com/vchoutas/smplify-x)
- The method for fitting 3D skeleton and SMPL model is similar to [SMPLify-X](https://github.com/vchoutas/smplify-x)(with 3D keypoints loss), [TotalCapture](http://www.cs.cmu.edu/~hanbyulj/totalcapture/)(without using point clouds).
EasyMocap is **built by** researchers from the 3D vision group of Zhejiang University: [**Qing Shuai**](https://chingswy.github.io/), [**Qi Fang**](https://raypine.github.io/), [**Junting Dong**](https://jtdong.com/), [**Sida Peng**](https://pengsida.net/), **Di Huang**, [**Hujun Bao**](http://www.cad.zju.edu.cn/home/bao/), **and** [**Xiaowei Zhou**](https://xzhou.me/).
We would like to thank Wenduo Feng, Di Huang, Yuji Chen, Hao Xu, Qing Shuai, Qi Fang, Ting Xie, Junting Dong, Sida Peng and Xiaopeng Ji who are the performers in the sample data. We would also like to thank all the people who has helped EasyMocap [in any way](https://github.com/zju3dv/EasyMocap/graphs/contributors).
