erode edit page

do morphological erosion of pixels based on neighbor counts

Syntax

ebsd = erode(ebsd,0)
ebsd = erode(ebsd,2,'titanium')
ebsd = erode(ebsd,1,{'a' 'b' 'notIndexed'})

Input

ebsd EBSD
counts upper threshold of same phase pixels around each pixel to permit erosion
phase phase name, cell or string

Output

ebsd EBSD without the eroded pixels

Example

mtexdata small plot(ebsd); hold on plot(ebsd('n'),'FaceColor','k'); hold off; mtexTitle('original'); nextAxis

% erode isolated, nonIndexed points ebsd = erode(ebsd,0); plot(ebsd); hold on plot(ebsd('n'),'FaceColor','k'); hold off; mtexTitle('no single nonIndexed pixels'); nextAxis

% erode isolated, nonIndexed points for i=1:10 ebsd = erode(ebsd,1,{'n' 'D' 'E'}); end

plot(ebsd); hold on plot(ebsd('n'),'FaceColor','k'); hold off; mtexTitle('no n,D,E \(\le\) 1 neighbors, 10 iter'); nextAxis

% erode isolated, nonIndexed points

for i=1:10 ebsd = erode(ebsd,2,{'n' 'D' 'E','F'}); ebsd = ebsd.fill; end

plot(ebsd); hold on plot(ebsd('n'),'FaceColor','k'); hold off; mtexTitle('no n,D,E \(\le\) 2 neighbors, filled,10 iter');
