Heartbeat Rate app allows to measure the pulse using video processing algorithm
Inspired by recent publication on a video processing algorithm
, which is able to detect and magnify subtle periodic changes in color in the series of video frames, DataArt has started experiments on adding heartbeat measurement possibility to their Microsoft Kinect-based healthcare solution.
The principle of detection is based on the fact that the human skin becomes more red when the blood pressure is at its maximum (systolic pressure), and less red when the pressure is at its minimum (diastolic pressure). For people not having arrhythmia, these changes are periodic, and therefore, its’ frequency can be caught and measured using spectrum analysis principles.
