VIBE
VIBE is a classic 3D pose esitmation methods. But the original version is very slow no matter on detction tracking or rendering. In this branch new version, I make it re-born.
The promote are:
- using YOLOv5 and DeepSort as tracking module, it's faster and accurator;
- using
realrender
for rending, discard old and stupid pyrender;

Features
Video Inference for Body Pose and Shape Estimation (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 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),
- 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
- 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:
git clone https://github.com/mkocabas/VIBE.git
Install the requirements using virtualenv
or conda
:
# 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:
source scripts/prepare_data.sh
Then, running the demo is as simple as:
# 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
for more details about the demo code.

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 and create an account.
- Download the Unity-compatible FBX file through the link
- 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 <male or female> \
--person_id <tracklet id from VIBE output>
Windows Installation Tutorial
You can follow the instructions provided by @carlosedubarreto to install and run VIBE on a Windows machine:
- VIBE windows installation tutorial: https://youtu.be/3qhs5IRJ1LI
- 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:
Training
Run the commands below to start training:
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
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
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.
