trim_saddle_points(peaks, dt, maxiter=20)[source]

Removes peaks that were mistakenly identified because they lied on a saddle or ridge in the distance transform that was not actually a true local peak.

  • peaks (ndarray) – A boolean image containing True values to mark peaks in the distance transform (dt)

  • dt (ndarray) – The distance transform of the pore space for which the peaks are sought.

  • maxiter (int) – The number of iteration to use when finding saddle points. The default value is 20.


image – An image with fewer peaks than the input image
