The Wavelet Transform

1993
Chapter 1 presented the concepts involved with wavelet theory, especially the scaling operation, and avoided all of the mathematical rigor. This section supports the conceptual statements by providing the mathematical justification. General, continuous-time wavelet transforms are initially discussed.

Discrete Lattice Wavelet Transform

IEEE Transactions on Circuits and Systems II: Express Briefs, 2007
The discrete wavelet transform (DWT) has gained a wide acceptance in denoising and compression coding of images and signals. In this work we introduce a discrete lattice wavelet transform (DLWT). In the analysis part, the lattice structure contains two parallel transmission channels, which exchange information via two crossed lattice filters.

Biorthogonal Wavelet Transforms

2014
Wavelets in the polynomial and discrete spline spaces were introduced in Chaps. 8 and 10, respectively. In both cases, the wavelets’ design and implementation of the transforms were associated with perfect reconstruction (PR) filter banks. In this chapter, those associations are discussed in more detail.

DieWavelet-Transformation

2010
Die Wavelet-Transformation wurde 1982 von Morlet et al. eingefuhrt, wobei die Anwendung in der Auswertung seismischer Messdaten bestand [115], [116]. Seither wurden verschiedene Arten der Wavelet-Transformation vorgeschlagen, und es haben sich viele weitere Anwendungen gefunden.
