wRidgeSampling {Rwave}R Documentation

Sampling wavelet Ridge

Description

Given a ridge phi (for the wavelet transform), returns a (appropriately) subsampled version with a given subsampling rate.

Usage

wRidgeSampling(phi, compr, nvoice)

Arguments

phi ridge (1D array).
compr subsampling rate for the ridge.
nvoice number of voices per octave.

Details

To account for the variable sizes of wavelets, the sampling rate of a wavelet ridge is not uniform, and is proportional to the scale.

Value

Returns a list containing the discrete values of the ridge.
node time coordinates of the ridge samples.
phinode scale coordinates of the ridge samples.
nbnode number of nodes of the ridge samples.
