1. qmf
filter may be obtained from MakeONFilter
.
2. usually, length(qmf) < 2^(L+1)
.
3. To reconstruct use IWT_TI
.
FWT_TI(x, L, qmf)
array of dyadic length n=2^J.
degree of coarsest scale.
orthonormal quadrature mirror filter.
TIWT
stationary wavelet transform table.
# NOT RUN {
x <- MakeSignal('Ramp', 8)
L <- 0
qmf <- MakeONFilter('Haar')
TIWT <- FWT_TI(x, L, qmf)
# }
