Jan Simon -
Excellent catch. Your simplification is ~1.2x faster. The code is now updated.

01 Mar 2014 Region Growing Segmentation by growing a region from seed point using intensity mean measure Author: Dirk-Jan Kroon

Thanks for the function. Good code to have in your image processing toolbox.

29 Jan 2014 Tools for NIfTI and ANALYZE image Load, save, make, reslice, view (and edit) both NIfTI and ANALYZE data on any platform Author: Jimmy Shen

great functions
thanks for the update

A simplification:

sw = (sesize-1)/2;
ses2 = ceil(sesize/2);
[y,x,z] = meshgrid(-sw:sw, -sw:sw, -sw:sw);
m = sqrt(x.^2 + y.^2 + z.^2);
b = (m <= m(ses2, ses2, sesize));
se = strel('arbitrary', b);

Nice work!
