Guest Editorial: Camera-Based Monitoring for Pervasive Healthcare Informatics
Wang W., Leonhardt S., Tarassenko L., Shan C., McDuff D.
This special issue of the IEEE Journal of Biomedical and Health Informatics journal presents and highlight some of the latest developments on applying camera-based techniques for pervasive healthcare informatics. It has attracted a great number of submissions from researchers both from academia and from industry. Five articles presented in this special issue focus on camera-based physiological measurement, applying novel signal- and image-processing techniques to improve the robustness of vital-sign measurement and having the systems validated in real-world use cases such as automotive and clinical practice. A general video-processing framework for camera-based pulse-rate measurement includes two common parts, such as frontends that pre-process images or post-process measured signals, and the core algorithm that extracts the photoplethysmography (PPG) signal from the optical signals.
