Query: iPhys: An Open Non-Contact Imaging-Based Physiological Measurement
  Toolbox   Imaging-based, non-contact measurement of physiology (including imaging
photoplethysmography and imaging ballistocardiography) is a growing field of
research. There are several strengths of imaging methods that make them
attractive. They remove the need for uncomfortable contact sensors and can
enable spatial and concomitant measurement from a single sensor. Furthermore,
cameras are ubiquitous and often low-cost solutions for sensing. Open source
toolboxes help accelerate the progress of research by providing a means to
compare new approaches against standard implementations of the
state-of-the-art. We present an open source imaging-based physiological
measurement toolbox with implementations of many of the most frequently
employed computational methods. We hope that this toolbox will contribute to
the advancement of non-contact physiological sensing methods.
