LIPSIA     Medial lines of sulci
vsulcogram
'vsulcogram' extracts medial lines of sulci from a white matter segmented image. This program uses a chain of processing modules (morphological filters, distance transforms, etc.) to extract the medial lines of sulci of an MR image of the human brain. The input image must be a white matter segmentation. The output will be a graph representing medial lines of the medial lines of sulci at a specified depth. The input image must be a binary image of type VBit. The output image will be of type VGraph.

Parameters of 'vsulcogram':
-help
Prints a message describing options.
-in
Specifies the Vista data file containing the input image.
-out
Specifies where to write the output image as a Vista data file.
-depth
