FWT_TI {rwavelet} | R Documentation |
Translation Invariant Forward Wavelet Transform
Description
1. qmf
filter may be obtained from MakeONFilter
.
2. usually, length(qmf) < 2^(L+1)
.
3. To reconstruct use IWT_TI
.
Usage

Arguments
x |
array of dyadic length n=2^J. |
L |
degree of coarsest scale. |
