Demo: "Neural PhysCap" Neural Monocular 3D Human Motion Capture with Physical Awareness

The implementation is based on Neural Monocular 3D Human Motion Capture with Physical Awareness
SIGGRAPH '21.

Authors: Soshi Shimada Vladislav Golyanik Weipeng Xu Patrick Pérez and Christian Theobalt

Dependencies

Python 3.7
Ubuntu 18.04 (The system should run on other Ubuntu versions and Windows, however not tested.)
RBDL: Rigid Body Dynamics Library (https://rbdl.github.io/). Tested on V.2.6.0. (Important: set "RBDL_BUILD_ADDON_URDFREADER " to be "ON" when you compile. Also don't forget to add the compiled rbdl library in your python path use it.)
pytorch 1.10.1
For other python packages, please check requirements.txt

Installation

Download and install Python binded RBDL from https://github.com/rbdl/rbdl
Install Pytorch 1.8.1 with GPU support (https://pytorch.org/) (other versions should also work but not tested)
Install python packages by:
```
  pip install -r requirements.txt
```

How to Run

Download pretrained model from here. Below, we assume all the pretrained networks are place under "../pretrained_neuralPhys/".
We provide a sample data under "sample_data" To run the code on our sample data, first go to root directory (neuralphyscap_demo_release) and run:
```
 python demo.py  --input_path sample_data/sample_dance.npy --net_path ../pretrained_neuralPhys/  --img_width 1280 --img_height 720
```

The predictions will be saved under "./results/"

To visualize the predictions, run:
```
 python Visualizations/simple.py 
```

How to Run on Your Data

Run OpenPose and save the prediction.

Process your openpose data to be compatible with NeuralPhyscap:

 python process_openpose.py --input_path /PATH/TO/OPENPOSE/JSON/FILE --save_path /PATH/TO/SAVE --save_file_name YOUR_DATA.npy

This will generate ".npy" input file to run NeuralPhyscap. Say we name the npy file "YOUR_DATA.npy".

Run NeuralPhyscap on the generated npy file:

 python demo.py  --input_path PATH/TO/YOUR_DATA.npy --net_path ../pretrained_neuralPhys/  --img_width IMAGE_WIDTH --img_height IMAGE_HEIGHT

Replace IMAGE_WIDTH and IMAGE_HEIGHT with your own video width and height (integer values)
