Remote photoplethysmography with constrained ICA using periodicity and chrominance constraints
BioMedical Engineering OnLine, 2018 Background Remote photoplethysmography (rPPG) has been in the forefront recently for measuring cardiac pulse rates from live or recorded videos. It finds advantages in scenarios requiring remote monitoring, such as medicine and fitness, where contact ...

Asset Pricing and Risk‐Sharing Implications of Alternative Pension Plan Systems
The Journal of Finance, EarlyView.ABSTRACT We show that incorporating defined benefit pension funds in an incomplete markets asset pricing model improves its ability to match the historical equity premium and riskless rate and has important risk‐sharing implications. We document the importance of the pension fund's size and asset demands, and a new risk channel arising from ...

Evaluating RGB channels in remote photoplethysmography: a comparative study with contact-based PPG
Frontiers in Physiology, 2023 Remote photoplethysmography (rPPG) provides a non-contact method for measuring blood volume changes. In this study, we compared rPPG signals obtained from video cameras with traditional contact-based photoplethysmography (cPPG) to assess the ...
