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=FALSE)

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.
