Trim Dyadic Wavelet Transform Extrema

Description

Trimming of dyadic wavelet transform local extrema, assuming normal distribution.

Usage

mntrim(extrema, scale=FALSE, prct=0.95)

Arguments

extrema dyadic wavelet transform extrema (output of ext).
scale when set, the wavelet transform at each scale will be plotted with the same scale.
prct

Details

The distribution of extrema of dyadic wavelet transform at each scale is generated by simulation, assuming a normal distribution, and the 95% critical value is used for thresholding the extrema of the signal.

Value

Structure containing
original original signal.
extrema trimmed extrema representation.
Sf coarse resolution of signal.
maxresoln number of decomposition scales.
np size of signal.
