Raw

Unsupervised Human Action Recognition with Skeletal Graph Laplacian and Self-Supervised Viewpoints Invariance

output

This repository provides the Pytorch code for our work accepted to BMVC 2021 as an Oral Presentation.

Code repository with training script for the NTU-60 and NTU-120 datasets.

Requirements

  • Numpy
  • Scikit-learn
  • Pytorch
  • Tqdm
  • Wandb

The code has been run on PyTorch version 1.6.0, and we therefore recommend this version.

Dataset preprocessing

  • NTU-60

    • Download zip file containing raw skeleton data here
    • Extract the nturgb+d_skeletons folder, contained inside zip file, to "dataset/raw/ntu_60"
    • Execute NTU60_dataset_preprocessing.py

  • NTU-120

    • Download zip files containing raw skeleton data here and here
    • Extract the nturgb+d_skeletons folders, contained inside zip files, to "dataset/raw/ntu_120"
    • Execute NTU120_dataset_preprocessing.py
