"""Separate segments from one VDF image using edge-detection by the
sobel transform and the watershed segmentation implemented in
scikit-image. See [1,2] for examples from scikit-image.
Parameters
----------
vdf_temp : np.array
One VDF image.
min_distance: int
Minimum distance (in pixels) between markers for them to be
considered separate markers for the watershed segmentation.
min_size : float
Grains with size (i.e. total number of pixels) below min_size
are discarded.
max_size : float
Grains with size (i.e. total number of pixels) above max_size
are discarded.
max_number_of_grains : int
Maximum number of grains included in the returned separated
grains. If it is exceeded, those with highest peak intensities
will be returned.
marker_radius : float
If 1 or larger, each marker for watershed is expanded to a disk
of radius marker_radius. marker_radius should not exceed
2*min_distance.
threshold : bool
If True, a mask is calculated by thresholding the VDF image by
the Li threshold method in scikit-image. If False (default), the
mask is the boolean VDF image.
exclude_border : int or True, optional
If non-zero integer, peaks within a distance of exclude_border
from the boarder will be discarded. If True, peaks at or closer
than min_distance of the boarder, will be discarded.
plot_on : bool
If True, the VDF, the mask, the distance transform
and the separated grains will be plotted in one figure window.
Returns
-------
sep : np.array
Array containing segments from VDF images (i.e. separated
grains). Shape: (image size x, image size y, number of grains)
