Eulerian Signal Processing Viewer

Simulating the core principles of non-contact physiological signal extraction from video.

Web-App Overview: Visualizing Signals

This viewer demonstrates the signal processing workflow central to techniques like Eulerian Video Magnification (EVM), as shown in the referenced video about detecting blood flow. The goal is to extract a weak, periodic signal (like a heartbeat, or **Pulse Rate Variability**) from noisy data, similar to how subtle color changes in skin are amplified to reveal the cardiac cycle.

The screen is divided into two main graphs:
