In fabnavarro/rwavelet: Wavelet Analysis

Invert 2-d Translation Invariant Wavelet Transform

Description

Invert 2-d Translation Invariant Wavelet Transform

Usage

IWT2_TI(tiwt, L, qmf)

Arguments

tiwt	translation-invariant wavelet transform table, (3(J-L)+1)n by n.
L	degree of coarsest scale.
qmf	orthonormal quadrature mirror filter.

Value

x 2-d image reconstructed from translation-invariant transform TIWT.

Examples

x <- matrix(rnorm(2^2), ncol=2)
L <- 0
qmf <- MakeONFilter('Haar')
TIWT <- FWT2_TI(x, L, qmf)
xr <- IWT2_TI(TIWT,L,qmf)
