#include "CVIPmorph.h"
Image *morphIterMod_Image(const Image *binImage, const
Matrix **surMATS, CVIP_BOOLEAN (*const
boolFUNC)(CVIP_BOOLEAN a,CVIP_BOOLEAN b), int no_of_sur, int
connectedness, int no_of_iter, int f)
<binImage> - pointer to Image structure (binary image)
<surMATS> - pointer to set S (surrounds) for which a_ij = 1
<boolFUNC> - pointer to Boolean function of form L(a,b)
(c_ij = L(a_ij,b_ij))
<no_of_sur> - number of surrounds
<connectedness> - the connectivity scheme being used; one
of...FOUR,EIGHT,SIX_NWSE,SIX_NESW.
<no_of_iter> - number of iterations to perform
<f> - number of subfields into which the image tesselation
will be divided

DESCRIPTION
Consider a_ij to have value one when the neighborhood of the
picture cell at (i, j) is in this set. Next consider b_ij to
denote the value of the picture cell itself. At each point
of the tessellated image a new binary value is computed that
is the result for that point of the iterative modification
algorithm. The new value c_ij is to be computed from a_ij
and b_ij. Here a, b, c are Boolean variables, in that the
they can only take on values of 0 or 1. Computation of c
from a and b can thus be specified by a Boolean function of
two variables -- <boolFUNC>. We can uniquely define the mor-
phological iterative modification algorithm by specifying
four things... (1) The set S of surrounds <surMATS> (for
which a_ij = 1), (2) The Boolean function L(a,b) (where c_ij
= L(a_ij,b_ij)), (3) The number of iterations <no_of_iter>,
n. (4) The number of subfields, <f>, into which the image
tessellation is divided. There are several Boolean functions
provided for the user (see functions zero, not_b, and, or,
not_and, or_not_and, xor.) In addition a set of hexagonal
lattices are provided and declared as HEXLAT1, HEXLAT2, ...,
HEXLAT14. The function array2Matrix can be used to form a
Matrix structure that can then be passed to morphomod(...).
