mmthick - Image transformation by thickening.

Synopsis

y = mmthick( f, Iab, n, theta, DIRECTION )

Input

f: Binary image (logical uint8).

Iab: Interval. Default: Homotopic thickening interval (mmhomothick).

n: Non-negative integer. Number of iterations. Default: Infinite (-1).

theta: Degrees of rotation: 45, 90, or 180. Default: 45.

DIRECTION: String. 'CLOCKWISE' or ' ANTI-CLOCKWISE' Default: "CLOCKWISE".

Output

y: Binary image (logical uint8).

Description

mmthick creates the binary image y by performing a thickening of the binary image f. The number of iterations of the thickening is n and each iteration is performed by union of f with the points that are detected in f by the hit-miss operators characterized by rotations of theta degrees of the interval Iab.

Equation

Algorithm

function y = mmthick_equ( f, Iab, n, theta, DIRECTION )
  y = f;
  for i=1:n
    for alpha=0:theta:360-theta
      Iab = mminterot(Iab, alpha, DIRECTION);
      y = mmunion(y,mmsupgen(y,Iab));
    end;
  end;
