dilation

public static int[][] dilation(int[][] matrix,
                               int n)

Returns the gray level dilation of the image represented by matrix.

Parameters:

matrix - a matrix of gray levels

n - the number used to calculate the size of the structuring element

Returns:

the dilation of matrix by the (2n+1)x(2 n+1) structuring element
