This is the code for the paper

Julieta Martinez, Rayat Hossain, Javier Romero, James J. Little. A simple yet effective baseline for 3d human pose estimation. In ICCV, 2017. https://arxiv.org/pdf/1705.03098.pdf.

The code in this repository was mostly written by Julieta Martinez, Rayat Hossain and Javier Romero.

We provide a strong baseline for 3d human pose estimation that also sheds light on the challenges of current approaches. Our model is lightweight and we strive to make our code transparent, compact, and easy-to-understand.

Dependencies

First of all

  1. Watch our video: https://youtu.be/Hmi3Pd9x1BE

  2. Clone this repository

git clone https://github.com/una-dinosauria/3d-pose-baseline.git
cd 3d-pose-baseline
mkdir -p data/h36m/
  1. Get the data

Go to http://vision.imar.ro/human3.6m/, log in, and download the D3 Positions files for subjects [1, 5, 6, 7, 8, 9, 11], and put them under the folder data/h36m. Your directory structure should look like this

src/
README.md
LICENCE
...
data/
  └── h36m/
    ├── Poses_D3_Positions_S1.tgz
    ├── Poses_D3_Positions_S11.tgz
    ├── Poses_D3_Positions_S5.tgz
    ├── Poses_D3_Positions_S6.tgz
    ├── Poses_D3_Positions_S7.tgz
    ├── Poses_D3_Positions_S8.tgz
    └── Poses_D3_Positions_S9.tgz

Now, move to the data folder, and uncompress all the data

cd data/h36m/
for file in *.tgz; do tar -xvzf $file; done

Finally, download the code-v1.2.zip file, unzip it, and copy the metadata.xml file under data/h36m/

Now, your data directory should look like this:

data/
  └── h36m/
    ├── metadata.xml
    ├── S1/
    ├── S11/
    ├── S5/
    ├── S6/
    ├── S7/
    ├── S8/
    └── S9/

There is one little fix we need to run for the data to have consistent names:

mv h36m/S1/MyPoseFeatures/D3_Positions/TakingPhoto.cdf \
   h36m/S1/MyPoseFeatures/D3_Positions/Photo.cdf

mv h36m/S1/MyPoseFeatures/D3_Positions/TakingPhoto\ 1.cdf \
   h36m/S1/MyPoseFeatures/D3_Positions/Photo\ 1.cdf

mv h36m/S1/MyPoseFeatures/D3_Positions/WalkingDog.cdf \
   h36m/S1/MyPoseFeatures/D3_Positions/WalkDog.cdf

mv h36m/S1/MyPoseFeatures/D3_Positions/WalkingDog\ 1.cdf \
   h36m/S1/MyPoseFeatures/D3_Positions/WalkDog\ 1.cdf

And you are done!

Please note that we are currently not supporting SH detections anymore, only training from GT 2d detections is possible now.

Quick demo

For a quick demo, you can train for one epoch and visualize the results. To train, run

python src/predict_3dpose.py --camera_frame --residual --batch_norm --dropout 0.5 --max_norm --evaluateActionWise --epochs 1

This should take about <5 minutes to complete on a GTX 1080, and give you around 56 mm of error on the test set.

Now, to visualize the results, simply run

python src/predict_3dpose.py --camera_frame --residual --batch_norm --dropout 0.5 --max_norm --evaluateActionWise --epochs 1 --sample --load 24371

This will produce a visualization similar to this:

Visualization example

Training

To train a model with clean 2d detections, run:

python src/predict_3dpose.py --camera_frame --residual --batch_norm --dropout 0.5 --max_norm --evaluateActionWise

This corresponds to Table 2, bottom row. Ours (GT detections) (MA)
