R: Reconstruct from Dyadic Wavelet Transform Extrema

mrecons {Rwave} | R Documentation

## 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.

### 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.

### References

See discussions in the text of “Practical Time-Frequency Analysis”.

### See Also

`mw`, `ext`.
