PROGRAM NAME
vdist - Distance Transform of a binary image
DESCRIPTION
vdist
will do the distance function of an input binary image.
Euclidean or City Block (4-connectivity or 8-connectivity) distance functions can be chosen.
REQUIRED ARGUMENTS
- -i
-
type: infile
desc: input image
- -cv
-
type: integer toggle
desc: dist. function
allowed values:
- 1 (euclidean),
- 4 (4-connectivity),
- or 8 (8-connectivity)
- -o
-
type: outfile
desc: resulting output image
OPTIONAL ARGUMENTS
none
EXAMPLES
vdist -i ball.xv -cv 4 -o outimage.xv
Will do the 4-connectivity City Block distance function of image "ball.xv", with the resulting image written to "outimage.xv".

RESTRICTIONS
vdist
The input image should be a binary image of the VIFF_TYP_1_BYTE (byte) data type (pixel values can be 0 or 255). The output image will be of the VIFF_TYP_2_BYTE (short) data type.
