Description (26 Sep 2013)

This code implements the face detection, tracking and descriptor extraction pipeline used in [1]. It includes the following parts :

  1. face detection
  2. shot boundary detection
  3. face tracking using point trajectories
  4. facial landmark localization
  5. facial descriptor extraction
  6. mouth motion estimation
  7. face-track kernel computation

The face detection (1.) is based on and includes pre-trained models from [3]. The rest of the pipeline is based on and includes code as well as pre-trained models from [2].

Acknowledgements: We graciously thank the authors of the previous code releases for making them available.

Dependencies

This code uses vlfeat v0.9.14. This version of the package can be downloaded from : http://www.vlfeat.org/download/vlfeat-0.9.14-bin.tar.gz

Running the code

To run this code you will need to have vl_feat working on your computer. In the main.m script modify the vl_feat_path to point to the vl_setup script.

vl_feat_path = '/path/to/vl_setup';

Unpack the dumped frames to a dump directory and specify the path in the main.m script in the dump_dir variable.

dump_dir = '/path/to/the/dump';

To compile the mex functions, run :

>>compile

To launch the demo of the pipeline on the short sequence of buffy, type :
