VSFITVisionX V4
NAME
vsfit − VisionX script for segmenting the juxtapleural pulmonary nodules
NAME SYNOPSISvsfit [if=<infile>] [ig=<infile>] [of=<outfile>] [th=<value>] [sf=<file>] [tk=<value>] [s=<value> [sd=<value>] [ic=<value>] [m=<value>] -e -v -neg -od -f
DESCRIPTIONVsfit segments the juxtapleural pulmonary nodule from a gray scale region of interest image in byte format. The output is a binary image containing the nodule region
OPTIONS (standard operation)|
if= |
input file name -- the region of interest image | ||
|
ig= |
the thresholded nodule (for -e option) | ||
|
of= |
output image: the nodule region is set to 255 the rest of the points are set to zero.(requires some post processing) | ||
|
ic= |
coordinates of a point inside the nodule | ||
|
s= |
size of morphological filter used for vessel removal |
|
m= |
surface model options are pl->planar qd->quadratic cu->cubic qr->fourth order (default: CU) | ||
|
sf= |
the surface file output | ||
|
tk= |
thickness of the surface drawn if the -od option is set if -od is not set than a layer of width "tk" around the surface function is excluded from the nodule segmentation (default: 2) | ||
|
sd= |
size of morphological filter used for post processing set to (default: set to value of s) | ||
|
th= |
threshold (not used for -e) default=100 | ||
|
-e |
use an existing thresholded/segmented image as input | ||
|
-v |
verbose mode | ||
|
-neg |
outputs a 3 level image with lung parenchyma, thoracic wall and nodule at different gray levels | ||
|
-od |
outputs an image with the pleural surface drawn on top | ||
|
-f |
keep temp files |
|
vplfit |
the C program for surface fitting using linear regression | ||
|
v3grad |
3D gradient operator used to find the average surface normal |
vsborder
small utility program to set the pixel values to zero at the boundaries of the image
