grainBoundaryCriterion Abstract base class for EBSD grain boundary criteria

A grainBoundaryCriterion decides, for pairs of neighboring EBSD pixels, whether the edge between them is a grain boundary.

The public API is

out = criterion.evaluate(ebsd,i,j)

where i and j are equally sized arrays of neighboring pixel indices.

The output out must have the same size as i and j. The convention is:

out = 1    no grain boundary
out = 0.5  low-angle grain boundary
out = 0    high-angle grain boundary

Subclasses implement the protected method doEvaluate.

Syntax

grains = calcGrains(ebsd,gbcAngle(10*degree))
out = criterion.evaluate(ebsd,i,j)

Input

ebsd EBSD
i, j equally sized arrays of neighbouring pixel indices

Output

out one value per pair, between 0 and 1

Derived Classes

gbcAngle threshold on the misorientation angle
gbcSoft a smooth transition instead of a threshold
gbcFMC fast multiscale clustering
gbcVariants boundaries between variants of a parent grain
gbcCustom criterion given by a function handle
