FTWT2_PO: 2-d tensor wavelet transform (periodized, orthogonal).
In fabnavarro/rwavelet: Wavelet Analysis
FTWT2_PO R Documentation
2-d tensor wavelet transform (periodized, orthogonal).
Description
A two-dimensional Wavelet Transform is computed for the array x.
qmf filter may be obtained from MakeONFilter.
To reconstruct, use ITWT2_PO.
Usage
FTWT2_PO(x, L, qmf)
Arguments
x
2-d image (n by n array, n dyadic).
L
coarse level.
qmf
quadrature mirror filter.
Value
wc 2-d wavelet transform.
See Also
ITWT2_PO, MakeONFilter.
Examples
qmf <- MakeONFilter('Daubechies', 10)
L <- 0
x <- matrix(rnorm(2^2), ncol=2)
wc <- FTWT2_PO(x, L, qmf)
