Description

Given a ridge phi (for the Gabor transform), returns a (regularly) subsampled version of length nbnodes.

Usage

RidgeSampling(phi, nbnodes)

Arguments

phi
ridge (1D array).
nbnodes
number of samples.

Value

  • Returns a list containing the discrete values of the ridge.
  • nodetime coordinates of the ridge samples.
  • phinodefrequency coordinates of the ridge samples.

Details

Gabor ridges are sampled uniformly.
