[mmintershow] [Up] [mmse2hmt] Intervals (hit-or-miss templates)

mmse2interval
Create an interval from a pair of structuring elements.

Synopsis

Iab = mmse2interval( a, b )

Implemented in Python.

Input

a Structuring Element

Left extremity.
b Structuring Element

Right extremity.

Output

Iab Interval

Description

mmse2interval creates the interval [a,b] from the structuring elements a and b such that a is less or equal b.

Equation

Flat interval:
Where W is a finite rectangle.
Non-flat interval:

Limitations

Both structuring elements must have the same size with odd dimensions. To avoid this limitation, use mmse2hmt.

Source Code

def mmse2interval(a, b):
    Iab = (a,mmneg(b))
    return Iab
