Thresholding

This module contains vairous thresholding routines, including hysteresis thresholding.

Module towards smart thresholding routines.

new_get_distutils_extension(modname, pyxfilename, language_level=None)

threshold(source, sink=None, threshold=None, hysteresis_threshold=None, seeds=None, background=None)

Hysteresis thresholding.

Arguments

sourcearray

Input source.

sinkarray or None

If None, a new array is allocated.

thresholdfloat

The threshold for the initial seeds.

hysteresis_thresholdfloat or None

The hysteresis threshold to extend the initial seeds. If None, no hysteresis thresholding is performed.

seedsarray or None

The seeds from which to start the hysteresis thresholds

backgroundarray or None

Exclude this area from the hysteresis thresholding.

Returns

sinkarray

Thresholded output.
