Noncontact Extraction of Human Arterial Pulse with a Commercial Digital Color Video Camera

TL;DRAbstract

Noncontact Extraction Of Human Arterial Pulse\nWith A Commercial Digital Color Video Camera\n\nMaria I. Davila, Ph.D.\nDepartment of Bioengineering\nUniversity of Illinois at Chicago\nChicago, Illinois (2012)\n\nDissertation Chairperson: Dr. Stephen W. Porges\n\nThe current study introduces and evaluates digital color video as a noncontact technology that can be applied to accurately extract human arterial pulse, respiration rate, and arterial pulse amplitude, during a variety of challenges.\nThe first objective was to understand the physiological significance of the features of the pulse signal extracted from digital color video technology by researching the interaction of the key components in the system (subject physiology, camera, and incident light). Once the dynamic relationship among the components was understood, the second objective was to validate the derived measures against criterion signals. The third objective was to develop a reliable system capable of delivering physiol
