Weights and data


🚩 Google drive link

Model Weights

We provide the pretrained rich and prox models for evaluation under the release folder.

RICH/PROX dataset

Evaluation

  1. You need to agree and follow the RICH dataset license and the PROX dataset license to use the data.

  2. Here, we provide the minimal and pre-propcessed RICH/sahmr_support and PROX/quantitative/sahmr_support for reproducing the metrics in the paper. By downloading, you agree to the RICH dataset license and the PROX dataset license.

Training ✨

  1. You need to submit a request to the authors from MPI and use their links for downloading the full datasets.

  2. RICH: We use the JPG format image. We downsampled the image to one-forth of its original dimensions.

  • images_ds4: Please download the train and val datasets and downsample the images to one-forth of its original dimensions.

  • bodies: We provide the fitted smplh parameters for each image. We will shift to the original smplx parameters in the future.

  • metro_3dpw_state_dict.bin: You only need this if you want to do training.

    Download the pretrained weights of METRO 
    mkdir -p datasymlinks/checkpoints/metro
# See https://github.com/microsoft/MeshTransformer/blob/main/LICENSE
# See https://github.com/microsoft/MeshTransformer/blob/main/scripts/download_models.sh

# the RICH folder should contain the original RICH dataset in the training phase,
# and the `RICH/sahmr_support` is enough for evaluation
mkdir -p datasymlinks/RICH 
ln -s path-to-rich-sahmr_support datasymlinks/RICH/sahmr_support
# for the training parts, please refer to the folder structure above

# the `PROX/quantitative/sahmr_support` is enough for evaluation
mkdir -p datasymlinks/PROX/quantitative
ln -s path-to-prox-sahmr_support datasymlinks/PROX/quantitative/sahmr_support

Usage

Evaluation 
# RICH model
python tools/dump_results.py -c configs/pose/sahmr_eval/rich.yaml 
python tools/eval_results.py -c configs/pose/sahmr_eval/rich.yaml

# PROX model
python tools/dump_results.py -c configs/pose/sahmr_eval/prox.yaml
python tools/eval_results.py -c configs/pose/sahmr_eval/prox.yaml
Training 
# We provide a training example on RICH dataset
python train_net.py -c configs/pose/rich/rcnet.yaml 
python train_net.py -c configs/pose/rich/sahmr.yaml
