FingerPy

FingerPy is a algorithm using python, scipy and fft to measure, analyse and monitor heart-beat using only a video of the user's finger on a mobile cellphone camera.

Setup

On the repository directory: pip3 install -r requirements.txt

Usage

1. Record a video pressing your finger against the camera
2. Copy video to /samples
3. python3 main.py samples/your_video.mp4|avi|MOV

Example

Video on /samples

python3 main.py samples/test_finger.avi

Result:

(1) Number of Beats per minute | (2) Heart-rate variability in milliseconds | (3) Signal-to-noise ratio in decibels

• Upper plot show the intensity of brightness (y) over time (x)
• Lower plot show the spectrum density of the signal that is Potency (y) over frequency bucket (x)
