mmsesum
N-1 iterative Minkowski additions

Synopsis

function NB = mmsesum ( B , N )

Input

B Structuring Element

Default: 3x3 elementary cross
N Double Non-negative integer.

Default: 1

Output

NB Structuring Element

Description

mmsesum creates the structuring element NB from N - 1 iterative Minkowski additions with the structuring element B.

Examples

b = mmimg2se([1 1 1; 1 1 1; 0 1 0]);
