v3bfill − fill background of 2D or 3D binary images

v3bfill [-H] [if=<inputfile>] [of=<outputfile>] [-2d] [-i] [-d] [-v] [-c8]

V3bfill fills the border connected background region of a 2D or 3D binary image. The background value is zero and anything else is a foreground value. The new fill values is 255. A simple recucursive fill algorithm is used.

The input may be either a 2D image, or a sequence of 2D images. The output format is the same as the input format.

This program is implemented recursively and requires a very large amount of stack space for large images. For Solaris the stacksize shoud be set to a large value manually. For most other platforms the sacksize will be set by v3bfill itself.

if=<input filename>

Specifies the input filename.

of=<output file>

Specifies the output filename.

-2d

Specifies that each z-axis slice should be filled separately (2D operation).

-i

Invert the resulting image so that the background is black and the foreground is white.

-d

Fill enclosed voids in the image.

-v

Print verbose operation information.

-c8

Run assuming 8 connected boundaries (4 connected background) instead of 4 connected boundaries. Only implemented in 2D mode.
