Requirements

• cudnn
• PyTorch
• Python with h5py, opencv and progress
• Optional: tensorboard

Testing

• Download our pre-trained model and move it to models.
• Run python demo.py -demo /path/to/image [-loadModel /path/to/image].

We provide example images in images/. For testing your own image, it is important that the person should be at the center of the image and most of the body parts should be within the image.

Training

• Prepare the training data:

  • Download our pre-processed Human3.6M dataset here.
  • Run python GetH36M.py in src/tools/ to convert H36M annotations to hdf5 format.
  • Modify src/ref.py to setup the dataset path.

• Stage1: Train the 2D hourglass component for 60 epochs

python main.py -expID Stage1

Our results of this stage is provided here.

• Stage2: Train without Geometry loss (drop LR at 25 epochs)

python main.py -expID Stage2 -ratio3D 1 -regWeigh 0.1 -loadModel ../exp/Stage1/model_60.pth -nEpochs 30 -dropLR 25

• Stage3: Train with Geometry loss

python main.py -expID Stage3 -ratio3D 1 -regWeigh 0.1 -varWeight 0.01 -loadModel ../exp/Stage2/model_30.pth -LR 2.5e-5 -nEpochs 10
