rPPg has four main components in the process: Skin pixel selection, Signal extraction, Signal filtering, and Output calculations.
First, The face and facial features are detected though video imaging via smartphone/webcam camera.
Then, the average of each pixel colour (red, green, blue) of the face is measured over time. Subsequently, the AI detects noise from head motions, and generates our offered vital signs.
The results are then calculated and shown to you with 90-95% accuracy (our AI is constantly learning, improving on this number!)
