Parameters:
skeleton- Type: The path to an existing

Description
Select Skeleton Segments that are heterogeneous. Any Segment whose
homogeneity is less than the given threshold will
be selected.
Figure 6.55. Selecting Heterogeneous Segments
(a) A Skeleton containing some heterogeneous Segments. The
pixels have been grouped by color, so
Segments straddling two colors are inhomogeneous.
(b) After selecting with threshold=0.9, Segments
that are less than 90% homogeneous have been selected and are
marked by heavy green lines.
(c) The same, but with threshold=0.5. Only one
segment is selected. (Unless a segment crosses three or more
pixel categories, it is impossible for its homogeneity to be
less than 0.5.)
