FWT3_PO: 3-d MRA Forward Wavelet Transform (periodized, orthogonal)
In fabnavarro/rwavelet: Wavelet Analysis
FWT3_PO R Documentation
3-d MRA Forward Wavelet Transform (periodized, orthogonal)
Description
A three-dimensional wavelet transform is computed for the array x.
qmf filter may be obtained from MakeONFilter.
To reconstruct, use IWT3_PO.
Usage
FWT3_PO(x, L, qmf)
Arguments
x
3-d array (n by n by n array, n dyadic).
L
coarse level.
qmf
quadrature mirror filter.
Details
3-D counterpart of Donoho's FWT2_PO, original matlab code
Vicki Yang and Brani Vidakovic.
Value
wc 3-d wavelet transform.
See Also
IWT3_PO, MakeONFilter.
Examples
qmf <- MakeONFilter('Daubechies', 10)
L <- 3
x <- array(rnorm(32^3), c(32,32,32))
wc <- FWT3_PO(x, L, qmf)
