A method of grainBoundary.

split every segment into pieces of about length delta: the old vertices stay where they are and the new ones lie on the old segments, so the boundary keeps its shape and its length and only the sampling gets finer, which gives a smoothing that follows evenly spaced degrees of freedom. Every piece carries the grains, the phases, the pair of measurements and the misorientation of the segment it lies on; MATLAB’s grainBoundary.refine

Syntax

gB = gB.refine()

Pieces of half the median segment length.

gB = gB.refine(10)

Pieces of about 10 map units.

Description

A segment is split into round(length / delta) pieces, at least one. MATLAB resamples every chain at equal arc length between the vertices that must stay and takes a protect list; here every segment is split on its own, which keeps the old vertices, and there is no protect.

Input

gB grainBoundary

Keywords

keyword default description
delta None the length of the pieces in the units of the map, by default half the median segment length; 0 or less leaves the boundary as it is

Output

gB grainBoundary, the refined boundary
