IFWT_TI {waved} | R Documentation |
Inverse Forward Wavelet Transform (translation invariant).
Description
Compute the Inverse Forward Wavelet Transform of a signal $f$ for the Meyer wavelet (translation invariant).
Usage
IFWT_TI(f_fft, psyJ_fft, lev, thr, nn, SOFT = FALSE)
Arguments
f_fft |
vector of the Fourier coefficient of $f$ |
psyJ_fft |
vector of the Fourier coefficient of the Meyer wavelet. |
lev |
resolution level |
thr |
threshold (has lentgh=1) |
nn |
sample size |
SOFT |
if SOFT=TRUE, uses the soft thresholding policy as opposed to the hard (SOFT=FALSE, the default). |
Value
Inverse Forward Wavelet Transform of a signal $f$, after thresholding.
