Definitions from the Web

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:

  • Wavelets are widely used in digital watermarking techniques for copyright protection.
  • Image compression algorithms based on wavelets have revolutionized the field of digital imaging.
  • Understanding wavelet theory is essential for engineers working in the field of signal processing.

2. Local:

  • In our local community, wavelets are utilized in the development of advanced medical imaging technologies.
  • Local researchers have been exploring the applications of wavelets in speech recognition algorithms.
