This week, I focused on trying to clean up the signal from the webcam in order to get a clean reading of pulse rate.
This involved including Fast Fourier Transform (FFT) coding into my python code.
Te results were very clean for trials using a finger directly over a webcam as seen below
By the end of the week, I could pick up the pulse from a section of my forehead using the webcam, but the signal has a lot of noise around it.
Whoa! That is way too cool. What did you do different to pick up the pulse and what do you think you can do to help reduce the noise with the webcam?
