mirdwt | R Documentation |
Computes the inverse redundant discrete wavelet transform x
for
input signal y
using the scaling filter h
. (Redundant means
here that the sub-sampling after each stage of the forward transform has
been omitted.)
mirdwt(yl, yh, h, L)
yl |
Lowpass component |
yh |
Highpass components |
h |
Scaling filter to be applied |
L |
Number of levels in wavelet decomposition. In the case of a 1D signal, length(yl) must be divisible by 2^L; in the case of a 2D signal, the row and the column dimension must be divisible by 2^L. If no argument is specified, a full DWT is returned for maximal possible L. |
Returns a list with components:
x |
Finite length 1D or 2D signal |
L |
Number of levels in wavelet decomposition |
