A list of
wavelet related transforms:
-
Continuous wavelet transform (CWT)
-
Discrete wavelet transform (DWT)
-
Multiresolution analysis (MRA)
-
Lifting scheme
-
Binomial QMF (BQMF)
-
Fast wavelet transform (FWT)
-
Complex wavelet transform
- Non or
undecimated wavelet transform, the downsampling is omitted
-
Newland transform, an orthonormal basis of wavelets is formed from appropriately constructed top-hat filters in frequency space
-
Wavelet packet decomposition (WPD), detail coefficients are decomposed and a variable tree can be formed
-
Stationary wavelet transform (SWT), no downsampling and the filters at each level are different
-
e-decimated discrete wavelet transform, depends on if the even or odd coefficients are selected in the downsampling
-
Second generation wavelet transform (SGWT), filters and wavelets are not created in the frequency domain
-
Dual-tree complex wavelet transform (DTCWT), two trees are used for decomposion to produce the real and complex coefficients
-
WITS: Where Is The Starlet, a collection of a hundredth of wavelet names in -let and associated multiscale, directional, geometric, representations, from activelets to x-lets through
bandelets,
chirplets,
contourlets,
curvelets,
noiselets, wedgelets ...
