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.
node
time coordinates of the ridge samples.
phinode
scale coordinates of the ridge samples.
nbnode
number 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.
