NonActionShot

This repository contains:

• code for the CVPR 2016 paper

  • Yang Wang, Minh Hoai. "Improving Human Action Recognition by Non-action Classification".
  • [PDF] (http://www3.cs.stonybrook.edu/~cvl/content/papers/2016/nonaction_cvpr16.pdf)
  • Project Page

• non-action shot classifier

  • shotCLF.mat
  • learned from ActionThread
  • only based on iDTD + FV, without using CNN features
  • only used [inShot, outShot, <del>allVideo</del>] to represent a shot, which doesn't affect the performance.

• code for applying non-action shot classifier onto an entire episode

Usage (in Mac/Linux environment):

1. Download this repository
2. Download ActionThread using script
3. Install Matlab dependences listed here
4. Get C dependences using script, and compile them correctly. Also, Modify denseTrackBin in ./utils/Matlab/YW_IDTD.m to your own compiled binary.
5. Follow the order here to repeat experiments
