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.
