wRidgeSampling: 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.

Value

  • Returns a list containing the discrete values of the ridge.
  • nodetime coordinates of the ridge samples.
  • phinodescale coordinates of the ridge samples.
  • nbnodenumber of nodes of the ridge samples.

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.
