Pulse capture

Posted on by Robin Ding Leave a comment Medical Physics, Research, Test and Measurement

The application was designed for the real time contactless photoplethysmography of the human face by means of an ordinary webcam in ambient light environment

System requirements:
– AMD or Intel CPU with 2 cores and 2.6 GHz clock speed (or higher);
– 512 Mb of RAM (or higher);
– OS Microsoft Windows 10/8/7/XP, booth 32 and 64 bit versions;
– A RGB webcam (Logitech B910 is the best choice).

Features
  • Provides real time heart rate measurement (up to each second update);
  • Provides contactless heart rate measurement (up to several meters depends on lens);
  • Provides video file processing (.mp4, .wmv, .avi);
  • Measurement error depends on webcam quality, stationarity of illumination and CPU speed, but in most cases it is less than 5 bpm.
  • Provides a record of photoplethysmography signal from face skin.
  • Provides mapping of arterial pulse on image;
  • Analyze heart rate at rest by age and sex, statistic courtesy by USA National Health Statistics.
  • Estimates SpO2 and breah rate (but erelative error could be greater than 5 %);
