mrecons: Reconstruct from Dyadic Wavelet Transform Extrema

Description Usage Arguments Details Value References See Also

Description

Reconstruct from dyadic wavelet transform modulus extrema. The reconstructed signal preserves locations and values at extrema.

Usage

1
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.

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.
