Description

Compute the local extrema of the dyadic wavelet transform modulus.

Usage

ext(wt, scale=FALSE, plot=TRUE)

Arguments

wt

dyadic wavelet transform.

scale

flag indicating if the extrema at each resolution will be plotted at the same scale.

plot

if set to TRUE, displays the transform on the graphics device.

Value

Structure containing:

original

original signal.

extrema

extrema representation.

Sf

coarse resolution of signal.

maxresoln

number of decomposition scales.

np

size of signal.
