It uses the CDF 9/7 wavelet transform (developed by Ingrid Daubechies in 1992) for its lossy compression algorithm, and the LeGall-Tabatabai (LGT) 5/3 wavelet transform (developed by Didier Le Gall and Ali J. Tabatabai in 1988) for its lossless compression algorithm.

Who invented wavelet?

Wavelets are based on the fundamental theory of expressing a complicated function by a set of self-similar functions by superpositioning, a principle introduced by Joseph Fourier in the 1800s.

What is wavelet transform used for?

The wavelet transform (WT) can be used to analyze signals in time–frequency space and reduce noise, while retaining the important components in the original signals.
