This review provides an overview of imaging photoplethysmography for the contactless acquisition of cardiovascular parameters, particularly heart rate.
Does not support routine clinical adoption of contactless monitoring; leaves open needs for validation and standardization.
Over the last few years, the contactless acquisition of cardiovascular parameters using cameras has gained immense attention. The technique provides an optical means to acquire cardiovascular information in a very convenient way. This review provides an overview on the technique's background and current realizations. Besides giving detailed information on the most widespread application of the technique, namely the contactless acquisition of heart rate, we outline further concepts and we critically discuss the current state.
