wRidgeSampling {Rwave}

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.
