If wc
is the result of a forward 2d wavelet transform,
with wc <- FTWT2_PO(x,L,qmf)
, then x <- ITWT2_PO(wc,L,qmf)
reconstructs x
exactly.
qmf
is a nice qmf, e.g. one made by MakeONFilter
.
1 | ITWT2_PO(wc, L, qmf)

wc |
2-d wavelet transform (n by n array, n dyadic). |
L |
coarse level. |
qmf |
quadrature mirror filter. |
x
2-d signal reconstructed from wc.
