Abstract

Multi-wavelength cameras play an essential role in remote photoplethysmography (PPG). Whereas these are readily available for visible light, this is not the case for near infrared (NIR). We propose to modify existing RGB cameras to make them suited for NIR-PPG. In particular, we exploit the spectral leakage of the RGB channels in infrared in combination with a narrow dual-band optical filter. Such camera modification is simple, cost-effective, easy to implement, and it is shown to attain a pulse-rate extraction performance comparable to that of multiple narrow-band NIR cameras.
