Description Usage Arguments Details Value See Also Examples
A three-dimensional wavelet transform is computed for the array x.
qmf
filter may be obtained from MakeONFilter
.
To reconstruct, use IWT3_PO
.
1 | FWT3_PO(x, L, qmf)
|
x |
3-d array (n by n by n array, n dyadic). |
L |
coarse level. |
qmf |
quadrature mirror filter. |
3-D counterpart of Donoho's FWT2_PO, original matlab code Vicki Yang and Brani Vidakovic.
wc
3-d wavelet transform.
1 2 3 4 | qmf <- MakeONFilter('Daubechies', 10)
L <- 3
x <- array(rnorm(32^3), c(32,32,32))
wc <- FWT3_PO(x, L, qmf)
