Syntax

ebsd = smooth(ebsd)

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

Input

`ebsd`	`EBSD`
`F`	`EBSDFilter`
`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] = calcGrains(ebsd,'minPixel',4);

ebsd = EBSDsquare (y↓→x, row↓→col)
