In the era of automation, an automatic and noninvasive tool is required for day-to-day health monitoring. Cardiac pulse being one of the vital physiological parameters has drawn attention of researchers for its measurement. In this article, the authors present an approach for automatic cardiac pulse measurement, using a typical webcam. In the presented approach, face region is detected and RGB traces are retrieved for the face region. FFT is applied on the extracted traces to compute power spectrum of the respective traces. The peaks of the power spectrum limited in the band region (0.75–4 Hz) are investigated to provide cardiac pulse measurement. The presented approach is hassle free in nature, and hence, can be adopted even in home environment. Experimental results represent the efficacy of the proposed approach.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
