fit ellipses to grains using the method described in Mulchrone& Choudhury,2004 (https://doi.org/10.1016/S0191-8141(03)00093-2)
Syntax
[c,a,b] = fitEllipse(grains);
plotEllipse(c,a,b,'lineColor','r')Input
| grains | grain2d |
Output
| c | centroid |
| a | long axis |
| b | short axis |
Options
| boundary | scale to fit boundary length |
Example
mtexdata csl grains = calcGrains(ebsd('indexed')) grains = smooth(grains,10) plot(ebsd('indexed'),ebsd('indexed').orientations,'micronbar','off') hold on plot(grains.boundary,'lineWidth',2) [c,a,b] = fitEllipse(grains(grains.numPixel>20)); plotEllipse(c,a,b,'lineColor','w','lineWidth',2) hold off
