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

mmsupcanon
Union of sup-generating or hit-miss operators.

Synopsis

y = mmsupcanon( f, Iab, theta = 45, DIRECTION = "CLOCKWISE" )

Implemented in Python.

Input

f Image Binary image.
Iab Interval
theta Double

Degrees of rotation: 45, 90, or 180.

Default: 45

DIRECTION String

'CLOCKWISE' or ' ANTI-CLOCKWISE'

Default: "CLOCKWISE"

Output

y Image Binary image.

Description

mmsupcanon creates the image y by computing the union of transformations of the image f by sup-generating operators. These hit-miss operators are characterized by rotations (in the clockwise or anti-clockwise direction) of theta degrees of the interval Iab.

Equation

Source Code

def mmsupcanon(f, Iab, theta=45, DIRECTION="CLOCKWISE"):
    from string import upper
    DIRECTION = upper(DIRECTION)            
    y = mmintersec(f,0)
    for t in range(0,360,theta):
        Irot = mminterot( Iab, t, DIRECTION )
        y = mmunion( y, mmsupgen(f, Irot))
    return y
