Remote and Non-Contact Estimation of Blood Pressure Variability Using Video Cameras

Abstract

Video pulse waves can be extracted from a green component included in video signals of a human body taken with a video camera. The video pulse wave is superior to photoelectric-plethysmogram (PPG) because the video pulse wave can provide us with two dimensional pulsatile information of blood perfusion under the skin in a remote and non-contact fashion. In the presentation, methods of estimation of blood pressure variability by using video pulse waves will be introduced, and methods of overcoming the defects of the video pulse wave such as sensitivity of body movement and light intensity will be discussed.
