Subspace Clustering for Action Recognition with Covariance Representations and Temporal Pruning

PWC PWC PWC PWC

output

This repository provides the supporting code for our work accepted to ICPR 2020

Code repository with demo script for the UTKinect dataset. /Data folder contains only the UTKinect dataset, to download and test other datasets, download the full package here.

Requirements

  • Ncut: extract the files from the folder of the downloaded zip file into the /Ncut folder and follow the instructions contained into the README.txt file for a complete installation.
  • SSC_ADMM: extract the files from the folder of the downloaded zip file into the /Codes_SSC folder.
  • TSC: extract the files from the "TSC/Codes" folder of the downloaded zip file into the /Codes_TSC folder.
  • If you encounter issues on Ncut scripts, remove all files and, instead, use the ones provided inside the "TSC/Codes/ncut" folder.
  • If you encounter issues on normalize.m and plotClusters.m, remove both files from /Codes_TSC folder.
  • compacc.m: retireve the script here and put it into the /Codes_TSC folder.

The code has been runned on MATLAB R2019b and we therefore recommend this version.
