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
  • fthe reconstructed signal.
  • greconstructed signal plus mean of original signal.
  • hreconstructed 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.
