wavelets
Tiny water undulations
Wavelets are small waves, especially ripples on water: Wavelets lapped against the hull.
In mathematics and signal processing, wavelets are wave-like functions used to analyze data at different scales—useful for image compression, audio processing, and detecting patterns in complex signals.
The mathematical sense draws on the image of localized, short-duration oscillations.
