- function [L,num] = spm_bwlabel(BW,n)
- % Label connected components in 2D or 3D binary images - a compiled routine
- %
- % FORMAT [L,num] = spm_bwlabel(BW,n)
- % BW - 2D or 3D binary image to perform labelling on.
- % n - connectivity criterion: 6 (surface), 18 (edge) or 26 (corner).
- % [Default: 18].
- % (for a 2D image these correspond to 4, 8 and 8 respectively).
- %
- % L - connected component image, i.e. image where each non-zero voxel
- % in BW will have a value corresponding to its label.
- % num - number of connected components in L.
