VTBBOXVisionX V4
NAME
vtbbox − return a tight bounding box around a image ROI
SYNOPSISvtbbox if= [z=] [-2d] [-w] [-sh] [-c] [-f] [-v]
DESCRIPTIONvtbbox finds a tight bounding box (bbx) around the non-zero region of the input. By default, the 3D bbx is considered. If -2d is specified, the 2D bbx is output for each axial slice. If z= is specified, the 2D bbx for the specified slice is output. The low and high frame numbers can be output instead of zl= and zh= coordinates using -f option.
The points of interest are defined to be points located at the bbx (i.e, with coordinates of x=xl, x=xh, y=yl, y=yh, z=zl or z=zh). If -c is specified, the coordinates of the points of interest are output.
vtbbox is a replacement for vlngwind which is now depreciated. ; is now used as separator for the -sh flag.

The -w and -sh
options return the results as sets of variables suitable for
the evaluation by the respective interpreters.
xl, xh, yl, yh, zl, zh
tight bbx of the input non-zero regions. E.g. xl is the lowest x coordinate of the input non-zero region; xh is the highest x coordinate of the input non-zero region.
xlx, xly, xlz
coordinates of the point of interest that are located at x = xl. Note that only point is output, although there may be multiple points with x = xl.
xhx, xhy, xhz
coordinates of the point of interest that are located at x = xh. Note that only point is output, although there may be multiple points with x = xh.
ylx, yly, ylz
coordinates of the point of interest that are located at y = yl. Note that only point is output, although there may be multiple points with y = yl.
yhx, yhy, yhz
coordinates of the point of interest that are located at y = yh. Note that only point is output, although there may be multiple points with y = yh.
zlx, zly, zlz
coordinates of the point of interest that are located at z = zl. Note that only point is output, although there may be multiple points with z = zl.
zhx, zhy, zhz
coordinates of the point of interest that are located at z = zh. Note that only point is output, although there may be multiple points with z = zh.
