Some components of the toolbox of algorithms use additional open source components. Specifically, the QRS detector used was written by Prof. Gari Clifford, and is available here . The PPG pulse peak detector was implemented by Dr Marco Pimentel. The signal quality indices were written by Dr Christina Orphanidou. Finally, the Principal Component Analysis technique uses code from the LS-SVMlab toolbox, written by the group at K.U. Leuven university.
