A Study of Projection-Based Attentive Spatial-Temporal Map for Remote Photoplethysmography Measurement. [PDF]
Bioengineering (Basel), 2022 The photoplethysmography (PPG) signal contains various information that is related to CVD (cardiovascular disease). The remote PPG (rPPG) is a method that can measure a PPG signal using a face image taken with a camera, without a PPG device.
