the heads a coarsening may not dissolve: the end of an open chain is a junction and stays where it is, a vertex where the pair of grains changes is a corner of both grain polygons even where only two segments meet there, and a protected vertex is one another boundary over the same vertices still walks over

Syntax

keep = mustKeep(gB)

The junctions and the corners.

keep = mustKeep(gB, protect=grains.sharedVertices())

And the vertices the inner boundary uses.

Description

A row is the head of a segment, its vertex gB.F[:, 1]; reduce and simplify keep the rows marked and may dissolve the others.

Input

gB grainBoundary

Keywords

keyword default description
protect None the ids of vertices that must stay as well

Output

keep a boolean per segment, whether its head must stay
