PROGRAM NAME

vthick - Thickening

DESCRIPTION

vthick will do the thickening of an input image by two set structuring elements.

The output image data type will be the same as that of the highest data type of the input image.

Some useful pairs of structuring elements:

0 0 0 1 1 1 Conditional Segmentation 0 1 0 0 0 0 1 1 1 0 0 0

0 0 0 1 0 0 Pseudo Convex Hull 0 1 1 1 0 0 0 0 0 1 0 0

1 0 0 0 0 0 Convex Hull 1 0 0 0 1 0 1 0 0 0 0 0

0 0 0 1 1 1 Homotopic Pruning 0 1 0 1 0 1 0 0 0 1 1 1

REQUIRED ARGUMENTS

-i
type: infile
desc: input image
-str1
type: infile
desc: Structuring Element
-str2
type: infile
desc: Structuring Element
-o
type: outfile
desc: resulting output image

OPTIONAL ARGUMENTS

none

EXAMPLES

vthick -i ball.xv -str1 b272.str -str2 b273.str -o outimage.xv

Will do the thickening of image "ball.xv" by the structuring set b272.str and b273.str, with the resulting image written to "outimage.xv".

RESTRICTIONS

vthick can be defined for all data types supported by Khoros, but at the moment it has been implemented just for the bit and unsigned char types. The structuring elements are subsets of the 3x3 matrix and the origin is always at the center of this matrix.
