mrecons: Reconstruct from Dyadic Wavelet Transform Extrema
Description
Reconstruct from dyadic wavelet transform modulus extrema. The reconstructed signal preserves locations and values at extrema.
Usage
mrecons(extrema, filtername="Gaussian1", readflag=TRUE)
Arguments
extrema
the extrema representation.
filtername
filter used for dyadic wavelet transform.
readflag
if set to T, read reconstruction kernel from precomputed file.
Value
Structure containing
f
the reconstructed signal.
g
reconstructed signal plus mean of original signal.
h
reconstructed signal plus coarse scale component of original signal.
Details
The reconstruction involves only the wavelet coefficients, without taking care of the coarse scale component. The latter may be added a posteriori.
