Optical and Heart Monitoring Using Facial Image Processing and Fast Fourier Transform

Abstract

The prolonged use of Laptops, Mobile phones, and many digital screens, leads to many health issues such as damage of eyesight and unusual heart functioning. Our goal is to identify the cause and alert the user to take necessary precautions from excessive use of digital screens. By staring at the computer screen or while reading, our blink rate decreases by 60%. To prevent ocular conditions, we need to make the person blink when the blink rate is not enough. This software monitors and detects when the blinking rate is abnormal and recommends blinking eyes. The software uses video-based heart rate detection system to enable contact-free detection of a person's physical behaviour under relaxed and active conditions. This enables the person to protect themselves from dry eyes which leads to computer vision syndrome. Using a computer long time also leads to stress so the software uses the same video data to get the person's heart rate and alert the user when heart rate increases abnormally. Our system uses face detection for Region of Interest (ROI) constrained near-real-time signal analysis to detect the heart rate.
