Real-time Heart Rate Estimation using Live Video Feed
Heart rate (HR), the measure of how often the heart beats per minute, is influenced by the autonomic nervous system (ANS), which consists of two primary branches, the sympathetic and the parasympathetic nervous system.
Photoplethysmography (PPG) is a non-invasive optical technique that detects blood volume changes in the microvascular tissue bed beneath the skin.
Remote PPG (rPPG) is an evolution of PPG technology that no longer requires physical contact, relying instead on ambient light being reflected from the skin and captured remotely by a CMOS camera. The color signals captured can then be filtered using AI techniques.
All that is needed is a video camera, such as from a smartphone, and the doctors can assess their patients remotely in the most convenient and efficient way. It can help prioritize patients who are in immediate danger above others when used in conjunction with current hospital infrastructures such as appointment booking systems and waiting rooms. It can also help track changes in a patient’s vitals and keep track of their health journey. People in remote places who have no hospitals or clinics near them can use their mobile phones to connect with their providers and receive medical intervention when needed.
