Abstract
Non-contact HR measurement is getting active research area. Recently remote
photoplethysmography (rPPG) measurement based on simple skin optics model
has been proposed and it showed the effectiveness. In this paper, we propose
an accurate remote observation of the heart rate (HR) and heart rate variability
(HRV) based on hemoglobin component estimation which is based on detail
skin optics model. We perform experiments to measure subjects at rest and
under cognitive stress with the proposed method putting a polarized filter
in front of camera to evaluate the principal of the framework. From the
results of the experiments, the proposed method shows a high correlation
with the electrocardiograph (ECG) which is assumed as the ground truth.
We also evaluate the proposed method without putting any polarized filter
and confirm the usefulness for the remote observation of HRV which require
accurate detection of HR.
