## Features

_**V**ideo **I**nference for **B**ody Pose and Shape **E**stimation_ (VIBE) is a video pose and shape estimation method.

It predicts the parameters of SMPL body model for each frame of an input video. Pleaser refer to our [arXiv report](https://arxiv.org/abs/1912.05656) for further details.

This implementation:

- has the demo and training code for VIBE implemented purely in PyTorch,

- can work on arbitrary videos with multiple people,

- supports both CPU and GPU inference (though GPU is way faster),

- is fast, up-to 30 FPS on a RTX2080Ti (see [this table](doc/demo.md#runtime-performance)),

- achieves SOTA results on 3DPW and MPI-INF-3DHP datasets,

- includes Temporal SMPLify implementation.

- includes the training code and detailed instruction on how to train it from scratch.

- can create an FBX/glTF output to be used with major graphics softwares.



  

  



## Updates

- 05/01/2021: Windows installation tutorial is added thanks to amazing [@carlosedubarreto](https://github.com/carlosedubarreto)

- 06/10/2020: Support OneEuroFilter smoothing.

- 14/09/2020: FBX/glTF conversion script is released.

## Getting Started

VIBE has been implemented and tested on Ubuntu 18.04 with python >= 3.7. It supports both GPU and CPU inference.

If you don't have a suitable device, try running our Colab demo. 

Clone the repo:

```bash

git clone https://github.com/mkocabas/VIBE.git

```

Install the requirements using `virtualenv` or `conda`:

```bash

# pip

source scripts/install_pip.sh

# conda

source scripts/install_conda.sh

```

## Running the Demo

We have prepared a nice demo code to run VIBE on arbitrary videos. 

First, you need download the required data(i.e our trained model and SMPL model parameters). To do this you can just run:

```bash

source scripts/prepare_data.sh

```

Then, running the demo is as simple as:

```bash

# Run on a local video

python demo.py --vid_file sample_video.mp4 --output_folder output/ --display

# Run on a YouTube video

python demo.py --vid_file https://www.youtube.com/watch?v=wPZP8Bwxplo --output_folder output/ --display

```

Refer to [`doc/demo.md`](doc/demo.md) for more details about the demo code.

Sample demo output with the `--sideview` flag:



  



### FBX and glTF output (New Feature!)

We provide a script to convert VIBE output to standalone FBX/glTF files to be used in 3D graphics tools like

Blender, Unity etc. You need to follow steps below to be able to run the conversion script.

- You need to download FBX files for SMPL body model

    - Go to [SMPL website](https://smpl.is.tue.mpg.de/) and create an account.

    - Download the Unity-compatible FBX file through the [link](https://psfiles.is.tuebingen.mpg.de/downloads/smpl/SMPL_unity_v-1-0-0-zip)

    - Unzip the contents and locate them `data/SMPL_unity_v.1.0.0`.

- Install Blender python API

    - Note that we tested our script with Blender v2.8.0 and v2.8.3.

- Run the command below to convert VIBE output to FBX:

```

python lib/utils/fbx_output.py \

    --input output/sample_video/vibe_output.pkl \

    --output output/sample_video/fbx_output.fbx \ # specify the file extension as *.glb for glTF

    --fps_source 30 \

    --fps_target 30 \

    --gender  \

    --person_id 

``` 

### Windows Installation Tutorial

You can follow the instructions provided by [@carlosedubarreto](https://github.com/carlosedubarreto) to install and run VIBE on a Windows machine:

- FBX conversion: https://youtu.be/w1biKeiQThY

- Helper github repo: https://github.com/carlosedubarreto/vibe_win_install

## Google Colab

If you do not have a suitable environment to run this project then you could give Google Colab a try. 

It allows you to run the project in the cloud, free of charge. You may try our Colab demo using the notebook we have prepared: 

[![Open In Colab](https://colab.research.google.com/assets/colab-badge.svg)](https://colab.research.google.com/drive/1dFfwxZ52MN86FA6uFNypMEdFShd2euQA)

## Training

Run the commands below to start training:

```shell script

source scripts/prepare_training_data.sh

python train.py --cfg configs/config.yaml

```

Note that the training datasets should be downloaded and prepared before running data processing script.

Please see [`doc/train.md`](doc/train.md) for details on how to prepare them.

 

## Evaluation

Here we compare VIBE with recent state-of-the-art methods on 3D pose estimation datasets. Evaluation metric is

Procrustes Aligned Mean Per Joint Position Error (PA-MPJPE) in mm.

| Models         | 3DPW ↓ | MPI-INF-3DHP ↓ | H36M ↓ |

|----------------|:----:|:------------:|:----:|

| SPIN           | 59.2 |     67.5     | **41.1** |

| Temporal HMR   | 76.7 |     89.8     | 56.8 |

| VIBE           | 56.5 |     **63.4**     | 41.5 |

See [`doc/eval.md`](doc/eval.md) to reproduce the results in this table or 

evaluate a pretrained model.

**Correction**: Due to a mistake in dataset preprocessing, VIBE trained with 3DPW results in Table 1 of the original paper are not correct.

Besides, even though training with 3DPW guarantees better quantitative performance, it does not give good 

qualitative results. ArXiv version will be updated with the corrected results.
