IWT3_PO | R Documentation |
If wc
is the result of a forward 3-d wavelet transform, with wc <- FWT3_PO(x, L, qmf)
.
then x <- IWT3_PO(wc, L, qmf)
reconstructs x
exactly
qmf
is a nice qmf, e.g. one made by MakeONFilter
.
IWT3_PO(wc, L, qmf)
wc |
3-d wavelet transform (n by n by n array, n dyadic). |
L |
coarse level. |
qmf |
quadrature mirror filter. |
3-d counterpart of Donoho's IWT2_PO, original matlab code by Vicki Yang and Brani Vidakovic.
x
3-d signal reconstructed from wc.

qmf <- MakeONFilter('Daubechies', 10)
L <- 3
x <- array(rnorm(32^3), c(32, 32, 32))
wc <- FWT3_PO(x, L, qmf)
xr <- IWT3_PO(wc, L, qmf)
