smooth spatial EBSD

Syntax

ebsd = smooth(ebsd)
F = halfQuadraticFilter
F.alpha = 2;
ebsd = smooth(ebsd, F, 'fill', grains)

Input

ebsd EBSD
F @EBSDFilters
grains grain2d if provided pixels at the boundary between grains are not filled

Options

fill fill missing values (this is different then not indexed values!)
extrapolate extrapolate up the the outer boundaries

Example

mtexdata forsterite;
ebsd = ebsd('indexed');
% segment grains
[grains,ebsd.grainId] = calcGrains(ebsd);
ebsd = EBSD
