non-contact real-time heart rate monitoring system using Raspberry Pi 3 Model B

[salvazero]

Hello,

Is anyone working on the use of the Raspberry Pi Camera module as a heart rate sensor?
I am new to using Raspberry Pi. I want to build a non-contact real-time heart rate monitoring system using Raspberry Pi 3 Model B and Pi NoIR camera.

I found two related projects which are:
https://github.com/prouast/heartbeat
https://github.com/thearn/webcam-pulse-detector

Is it possible to build this system using Raspberry Pi? Also, Is it possible to calculate FFTs and FFTs on the Raspberry Pi?

Thanks for your time and consideration.

Hi,

Theoretically you can calculate an FFT by hand...for sure you can calculate it with a raspberry, too.
I wonder why do you bother...

But an FFT has some parameters:
* what bit width do you have
* what FFT size do you have
* what calculation speed do you expect?
