Camera-Based Remote Heart Rate Monitoring Using Photoplethysmography

Ensuring individuals' well-being through health monitoring is vital for safety and overall health. Monitoring vital signs, such as heart rate, is essential for understanding physiological conditions in diverse environments. Traditional methods often involve cumbersome and invasive equipment, making them impractical in confined or remote settings. As a result, there is growing interest in non-invasive, remote monitoring technologies that can track vital signs in real-time without compromising comfort or activities. This paper introduces a system utilizing camera-based photoplethysmography (PPG) technology for remote monitoring of vital signs. The system extracts and analyzes PPG signals from video footage captured by cameras, relying on advanced signal processing algorithms to accurately extract these signals despite challenges like motion artifacts and low signal-to-noise ratios. It employs techniques such as motion artifact removal, adaptive filtering, and real-time peak detection algorithms to improve PPG signal quality and reliability. The study demonstrates the system's capabilities in non-contact physiological monitoring and underscores its potential benefits in various settings. This research highlights the system's ability to extract critical health information using cameras, emphasizing its significance in maintaining individuals' health and well-being.
