Installation

• Clone this repository:

  git clone https://github.com/stevenlsw/Semi-Hand-Object.git
  

• Install the dependencies by the following command:

  pip install -r requirements.txt
  

Quick Demo (update soon)

Training and Evaluation on HO3D Dataset

Preparation

• Download the MANO model files (mano_v1_2.zip) from MANO website. Unzip and put mano/models/MANO_RIGHT.pkl into assets/mano_models.

• Download the YCB-Objects used in HO3D dataset. Put unzipped folder object_models under assets.

• The structure should look like this:

Semi-Hand-Object/
  assets/
    mano_models/
      MANO_RIGHT.pkl
    object_models/
      006_mustard_bottle/
        points.xyz
        textured_simple.obj
      ......

• Download and unzip HO3D dataset to path you like, the unzipped path is referred as $HO3D_root.

Evaluation

The hand & object pose estimation performance on HO3D dataset. We evaluate hand pose results on the official CodaLab challenge. The hand metric below is mean joint/mesh error after procrustes alignment, the object metric is average object vertices error within 10% of object diameter (ADD-0.1D).

In our model, we use transformer architecture to perform hand-object contextual reasoning.

Please download the trained model and save to path you like, the model path is refered as $resume.

• Testing with trained model

   python traineval.py --evaluate --HO3D_root={path to the dataset} --resume={path to the model} --test_batch=24 --host_folder=exp_results

The testing results will be saved in the $host_folder, which contains the following files:

• option.txt (saved options)
• object_result.txt (object pose evaluation performance)
• pred.json (zip -j pred.zip pred.json and submit to the offical challenge for hand evaluation)

Training

Please download the preprocessed files to train HO3D dataset. The downloaded files contains training list and labels generated from the original dataset to accelerate training. Please put the unzipped folder ho3d-process to current directory.

    python traineval.py --HO3D_root={path to the dataset} --train_batch=24 --host_folder=exp_results

The models will be automatically saved in $host_folder
