A method of grain2d.

the grains with their boundary and inner boundary refined, every segment split into pieces of about length delta; MATLAB’s grain2d.refineBoundary

Syntax

grains = grains.refineBoundary()

Pieces of half the median segment length.

grains = grains.refineBoundary(10)

Pieces of about 10 map units.

Description

The vertices stay where they are and the new ones lie on the old segments, so the grains keep their shape and only the sampling gets finer, which lets a following smoothBoundary move evenly spaced vertices. Both boundaries are refined over one pool of vertices.

Input

grains grain2d

Keywords

keyword default description
delta None the length of the pieces in the units of the map, by default half the median segment length of the boundary

Output

grains grain2d, the polygons traced again
