Imdilate de matlab en C

[LordofDestruction]

Buenas tardes amig@s, tengo unas dudas puntuales, resulta que tengo que realizar un programa que lea un arreglo bidimensional (matriz) con sólo elementos 1 y 0, tal como el tratamiento de una imagen binaria. Y a esta imagen, se le trate como matlab dilatandola con elemento estructurante. Ahí va mi duda.
Tengo lo siguiente:

Código:

#include <stdio.h>
int k,l;
short int matriz[18][42] =
{0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,1,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,1,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,1,1,1,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,1,1,1,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,0,0,1,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,1,1,1,1,1,0,0,0,0,0,0,0,0,0,0,0,0,1,1,1,0,0,1,1,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,1,1,1,1,1,0,0,0,0,0,0,0,0,0,0,0,0,1,1,1,1,1,1,1,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,1,1,1,0,1,0,1,1,1,0,0,0,0,0,0,0,0,

printf("\n\n");

}

y nada :(
Quien tiene alguna sugerencia?

Hola! tal vez si explicaras a que te referis con

se le trate como matlab dilatandola

seria mas facil ayudarte.... exactamente que es lo que hace "dilatandola" ??
