In this work, we present a real-time heart rate estimation method from a video using face detection, color-based signal extraction, and signal processing tech- niques. The proposed approach computes the heart rate by analyzing the color fluctuations in the facial region of interest (ROI). This report outlines the math- ematical formulation and results of the implementation.

This paper presents a real-time eye blink detection system using computer vision techniques and machine learning. The system uti- lizes the MediaPipe face mesh model for facial landmark detection and calculates the Eye Aspect Ratio (EAR) to determine the eye state. Results demonstrate high accuracy and responsiveness, indicating po- tential applications in driver drowsiness detection, human-computer interaction, and medical diagnostics.
