wRidgeSampling {Rwave} | R Documentation |
Given a ridge \phi
(for the wavelet transform), returns a
(appropriately) subsampled version with a given subsampling rate.
wRidgeSampling(phi, compr, nvoice)
phi |
ridge (1D array). |
compr |
subsampling rate for the ridge. |
nvoice |
number of voices per octave. |
To account for the variable sizes of wavelets, the sampling rate of a wavelet ridge is not uniform, and is proportional to the scale.
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. |
