Wavelet

Description:

A wavelet is a mathematical function that is used in signal processing and image compression. It is a small, localized wave pattern that can be analyzed and used to represent larger, more complex signals. Wavelets are particularly effective in analyzing signals with varying frequency content over time.

Senses:

1. Noun: A small, localized wave pattern used in signal processing and image compression.

2. Noun: A mathematical function used to represent larger, more complex signals.

3. Noun: A technique or algorithm that employs wavelets for signal analysis and processing.

Usages:

1. Popular:
