IWT2_TI {rwavelet}

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)
