I am experimenting with video-based visualizations of respiration, movements, and heartbeats during sleep:
“How to show 9 hours of sleep in 90 seconds”
My tech (ALT) + wavelet analysis.
Each frame of the video shows respiration and movements within a 30 seconds long time interval.
Respiration pattern (inhale/exhale) is typically within the [0.5; 2.5] interval on the vertical axis.
Relative ALT signal intensity for each video frame is shown by color according to the color scale on the right.
