spm_bwlabel: SPM: Connected component labelling in 2D or 3D - a compiled...
In jpellman/spmR: Statistical Parametric Mapping in R
Description
Usage
Arguments
Value
Description
The calling interface has been modelled on the
image processing toolbox routine bwlabel. See
the help for that routine for further information.
The implementation is not recursive (i.e. will not crash for
large connected components) and is losely based on
Thurfjell et al. 1992, A new three-dimensional connected
components labeling algorithm with simultaneous object
feature extraction capability. CVGIP: Graphical Models
and Image Processing 54(4):357-364.
Usage
1
FORMAT: [L,NUM] = spm_bwlabel(bw,conn)
Arguments
bw
(Binary) image to perform labelling on. Can
be 2 or 3D.
conn
Connectivity criterion. Could be 6(surface)
18(edge) or 26(corner). For a 2D bw these
correspond to 4, 8 and 8 respectively.
Value
A list containing: 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.
