Heart rate, an essential indicator of overall health and well-being, is traditionally measured by counting the number of cardiac pulses within a specific timeframe. Existing methods, however, require physical contact with the patient, which can lead to discomfort and skin-related issues. Now, researchers introduce an innovative non-contact approach that analyzes subtle color changes on the face to enable highly accurate heart rate estimation, even in scenes with ambient light fluctuations.
