[mmthreshad] [Up] [mminfgen] Sup-generating And Inf-generating

mminfcanon
Intersection of inf-generating operators.

Synopsis

function y = mminfcanon ( f , Iab , theta , DIRECTION )

Input

f Image Binary image
Iab Interval
theta Double

Default: 45

Degrees of rotation: 45, 90, or 180.
DIRECTION String

Default: 'CLOCKWISE'

Direction of rotation: 'CLOCKWISE' or ' ANTI-CLOCKWISE'

Output

y Image Binary image

Description

mminfcanon creates the image y by computing intersections of transformations of the image f by inf-generating (i.e., dual of the hit-or-miss) operators. These inf-generating operators are characterized by rotations (in the clockwise or anti-clockwise direction) of theta degrees of the interval Iab.

Equation

Algorithm

function y=mminfcanon_equ( f, Iab, theta, DIRECTION )
  y = ones(size(f));
  y = mmintersec(y,mminfgen(f, Iab));
  alpha = theta;
  while alpha < 360
    Irot = mminterot( Iab, alpha, DIRECTION );
    y = mmintersec(y,mminfgen(f, Irot));
    alpha = alpha + theta;
  end;
