The rise of photoplethysmography (PPG) in recent years has brought non-invasive cardiovascular monitoring into the spotlight, as it offers a unique approach to heart rate assessment by capturing blood volume variations over time. Furthermore, when it is preferable to avoid direct contact between the instrument and the subject, remote or non-contact PPG (rPPG) can be employed. This technique utilizes acquisition systems that eliminate the need for physical contact, such as cameras, to extract the rPPG signal by averaging pixel intensity over time. Not only has this technology been adopted in clinical settings, but also in other environments where monitoring vital parameters can offer advantages.
