What is the definition of wavelet in wavelet analysis
Answers
Answer:
Here's ur answer.....
Explanation:
A wavelet is a wave-like oscillation with an amplitude that begins at zero, increases, and then decreases back to zero. It can typically be visualized as a "brief oscillation" like one recorded by a seismograph or heart monitor. Generally, wavelets are intentionally crafted to have specific properties that make them useful for signal processing. Using a "reverse, shift, multiply and integrate" technique called convolution, wavelets can be combined with known portions of a damaged signal to extract information from the unknown portions.

Answer:
Explanation:
A wavelet is a mathematical function useful in digital signal processing and image compression . ... Wavelet compression works by analyzing an image and converting it into a set of mathematical expressions that can then be decoded by the receiver.
