mrecons: Reconstruct from Dyadic Wavelet Transform Extrema

In Rwave: Time-Frequency analysis of 1-D signals

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. This is not supported in the current package, and will cause an error.

Details

The reconstruction involves only the wavelet coefficients, without taking care of the coarse scale component. The latter may be added a posteriori.

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.
