摘要

Observing heart rate by electrocardiogram and oximetry sensors may cause skin irritation to some patients. In order to avoid this heart rate evaluation from face reflectance analysis is carried out. Initially procedure adapted is by taking face reflectance and details analysis is carried out. This results in changes in hemoglobin of blood vessels. The green channel is selected because hemoglobin observes only green colour. Hilbert-Huang transform is utilized to procure heart rate by reducing the light variations. Next to reduce noise EMD is applied. The proposed methodology is to get most accurate heart rate with some variations. With this approach, it is now possible to get heart rate accurate up to 70 %.
