PROGRAM NAME
vicanon - Inf-Canonical Operator
DESCRIPTION
vicanon
will do the n-canonical dual transformation of an input image by a set of n structuring elements, generated after two input structuring elements.
The number of structuring elements is the integer part of 8 (maximum number of struct. els. achieved by rotation of one struct. el.) divided by r (the rotation step).
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 0 0 0
End Points 0 1 0 1 0 1
0 0 0 1 1 1
0 0 0 1 1 1
Isolated Points 0 1 0 1 0 1
0 0 0 1 1 1
1 0 0 0 1 1
Triple Points 0 1 1 1 0 0
1 0 0 0 1 1
1 0 1 0 1 0
Triple Points 0 1 0 1 0 1
1 0 0 0 1 1
1 0 0 0 1 1
Triple Points 0 1 0 1 0 1
1 0 1 0 1 0

EXAMPLES
vicanon -i ball.xv -str1 b272.str -str2 b273.str -r 2 -o outimage.xv
Will do the n-canonical dual transformation of image "ball.xv" by a set of 4 structuring elements, generated after b272.str and b273.str, with the resulting image written to "outimage.xv".

RESTRICTIONS
vicanon
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.
