Non-contact video based estimation for heart rate variability using ambient light by extracting hemoglobin information
نویسنده
چکیده
In this paper, we propose the method of heart rate (HR) and heart rate variability (HRV) spectrogram estimation by analyzing extracted hemoglobin concentration from facial color images. Our method does not require any special camera. In addition, stable presumption is possible even under the ambient light sources. As a result, we could get HR around 99% accuracy and could get HRV spectrogram with the same accuracy of electrocardiogram. Therefore we could identify if participants were relaxed or stressed using conventional DSLR camera.

متن کاملRemote Measurement of Infant Emotion via Heart Rate Variability
Remote measurement of the blood volume pulse via imaging photoplethysmography (iPPG) using digital cameras and ambient light has great potential for healthcare and affective computing. This study introduces this iPPG method for detecting infant’s emotions pattern (discomfort and neutral) using video frames obtained from a low-cost webcam. Ten infants were obtained for heart rate(HR) and heart r...

Current technologies to allow continuous monitoring of vital signs in pre-term infants in the hospital require adhesive electrodes or sensors to be in direct contact with the patient. These can cause stress, pain, and also damage the fragile skin of the infants. It has been established previously that the colour and volume changes in superficial blood vessels during the cardiac cycle can be mea...
