He serves on planning committees for IEEE and SPIE, and has served on several advisory panels for the Department of Defence and the Department of Energy. ...
The ability to collect and process the signal, exploit the data for individual identification or verification, and disseminate the information depends on all three of these factors. ...
The reason for alignment is that most techniques rely on features derived from the morphology, amplitude, and timing of the heartbeat, thus requiring segmentation of individual beats. ...
