LIPSIA     White matter segmentation
vwhitematter
The program 'vwhitematter' computes a while matter segmentation. The input into this program MUST be a peeled image. It takes about 5 minutes of computation time. It is called as follows:

vwhitematter -in /home/newbdb/134/mr134_t1_pl.v -out mr134_wm.v


Note: For many data sets, white matter segmentations are already present in the MPI inhouse data base. They are called "/home/bdb/***/mr***_wm.v".

Parameters of 'vwhitematter':
-help
Prints usage information.
-in
Input file. Default: (none)
-out
Output file. Default: (none)
-t
threshold. Default: 3
-low
lower threshold. Default: 0
-high
upper threshold. Default: 0
-add
add to grey value thresholds. Default: 0
-auto [ true | false ]
Whether to use automatic threshold selection. Default: true
-geometry [ true | false ]
Whether to use geometrical constraints. Default: false
-iter
Max number of iterations. Default: 100
-wsize
Window size for local contrast enhancement (25 is a typical choice). Default: 0
-sigma
Sigma for local contrast enhancement. Default: 2
-topology [ true | false ]
Whether to enforce topological correctness . Default: false
