Interactive Blood Flow Velocity Simulation

Visualization Mode

Web App Overview

This interactive simulation demonstrates the principles of estimating two-dimensional blood flow velocity from video, inspired by the research presented by the Multimedia Computing Research Laboratory (MCRLab) at uOttawa. The original research shows how subtle, invisible color changes in human skin, caused by blood circulation, can be amplified and analyzed to reveal physiological information like heart rate and blood flow patterns.

This simulation creates a synthetic "skin patch" where you can observe these principles in action. You can control the heart rate, magnify the color changes, and switch between different visualization modes to understand the process from raw signal to a final velocity field map.

How to Use

The simulation is fully responsive and can be controlled with a mouse, keyboard (use Tab and Enter/Space), or touch gestures.

Future Directions

While this simulation provides a solid foundation for understanding the core concepts, future enhancements could include:
