Bob’s implementation of different rPPG algorithms

This module contains the implementation of different remote photoplesthymography (rPPG) algorithms:

• Li’s CVPR14 [li-cvpr-2014].
• CHROM [dehaan-tbe-2013].
• 2SR [wang-tbe-2015].

Also, we provide scripts to infer the heart-rate from the pulse signals, and to evaluate global performance on a database.

Note that this package was first meant to be used with the Manhob HCI-Tagging (http://mahnob-db.eu/hci-tagging/) and COHFACE (http://www.idiap.ch/dataset/cohface) databases, but could easily be extended to other datasets.

Warning

You should download the aforementioned databases before trying to run anything below!
