As a part of HAKE project (HAKE-3D). Code for our CVPR2020 paper "Detailed 2D-3D Joint Representation for Human-Object Interaction".

News: (2022.04.23) Two new works on HOI learning are releassed! Interactiveness Field (CVPR'22) and a new HOI metric mPD (AAAI'22).

(2021.1.15) Our extended version of TIN (Transferable Interactiveness Network) is accepted by TPAMI! New paper and code will be released soon.

(2020.10.27) The code of IDN (Paper) in NeurIPS'20 is released!

(2020.6.16) Our larger version HAKE-Large (>120K images, activity and part state labels) is released!

Ambiguous-HOI

This repo contains the code for the proposed Ambiguous-HOI dataset.

To collect the data set, run

bash script/Generate_Ambiguous_HOI.sh

After running this, the data and code related to Ambiguous-HOI would be organized as:

DJ-RN
├──Data
    ├── Ambiguous_HOI
        └── ...                  # The jpeg image files
    └── Test_ambiguous.pkl       # Person and object boudning boxes used by DJ-RN
└── -Results
    ├── gt_ambiguous_hoi_new.pkl # Annotation file
    └── Evaluate_HICO_DET.py     # Evaluation script

Run python ./-Results/Evaluate_ambiguous.py <your detection file> <path to save the result> to evaluate the performace. The detection file should be a pickle file with format of

{'xxx.jpg': # image file name
    [
        [x1, y1, x2, y2],        # Human bounding box
        [x1, y1, x2, y2],        # Object bounding box
        x,                       # Object category, 1~80
        np.array([xx, ..., xx]), # HOI detection score, np.array with size of (600,)
        x,                       # Human detection confidence
        x,                       # Object detection confidence
    ], 
    ...
}

bash script/Download_weight.sh
  1. Download inference results of our model. (Optional)
bash script/Download_result.sh

Data generation

  1. Run OpenPose for the images in the dataset. For HICO-DET, the OpenPose result could be downloaded from this link.

  2. Create the environment used for this phase.

conda create --name DJR-data --file requirements_data.txt
conda activate DJR-data
  1. Filter the OpenPose result.

python script/filter_pose.py --ori <path to your OpenPose result> --fil <path to save the filtered result>

  1. Run SMPLify-X on the dataset with the filtered pose.

  2. Assign the SMPLify-X results to the training and testing data.

python script/assign_pose_GT.py --pose <path to your pose used for SMPLify-X> --res <path to your SMPLify-X result>
python script/assign_pose_Neg.py --pose <path to your pose used for SMPLify-X> --res <path to your SMPLify-X result>

python tools/Train_HICO_DET_DJR.py --model <your model name> --num_iteration 400000

  1. Test and generate detection file on HICO-DET
python tools/Test_HICO_DET_DJR.py --model <your model name> --iteration 400000
python ./-Results/Generate_detection.py --model <your test output directory, under ./-Results by default>
  1. To evaluate the performance of our model on HICO-DET, run

python ./-Results/Evaluate_HICO_DET.py --file ./-Results/Detection_400000_DJR.pkl

  1. Test and generate detection file on Anbiguous-HOI

python tools/Test_ambiguous_DJR.py --model <your model name> --iteration 400000

  1. To evaluate the performance of our model on Ambiguous-HOI, run

python ./-Results/Evaluate_ambiguous.py ./-Results/400000_DJR_ambiguous.pkl DJR_ambiguous/

Tips

  1. As the data generation pipeline is long, you may find some useful common quetions in the issues.
  2. NaN loss: sometimes the training is not stable due to the align loss that needs careful tuning. We also recommend the MSE loss instead of KL divergence that can also achieve decent performance and is easier to train. More please refer to this issue.
