The following fits in at Step 3 above, and will fill holes between 80 and 300 pixels in area. L_candidate_holes = bwlabel(holes); stats = regionprops(L_candidate_holes, 'Area'); idx = find([stats.Area]>80 & [stats.Area]<300); midsized_holes = ismember(L_candidate_holes,idx); Just thought I'd share since I've been using this quite a bit recently. Of course, you could add more criteria to the regionprops call, and then select the holes based on more criteria too. Cheers, Sven. Hi Steve and all,

Just a little extra in case you want to fill *midsized* holes. The following fits in at Step 3 above, and will fill holes between 80 and 300 pixels in area.

L_candidate_holes = bwlabel(holes);
stats = regionprops(L_candidate_holes, ‘Area’);
idx = find([stats.Area]>80 & [stats.Area]<300);
midsized_holes = ismember(L_candidate_holes,idx);

Just thought I’d share since I’ve been using this quite a bit recently. Of course, you could add more criteria to the regionprops call, and then select the holes based on more criteria too.

Cheers,
Sven.
