[mminpos] [Up] [mmregmax] Connected Operators

mmopenrec
Opening by reconstruction.

Synopsis

y = mmopenrec( f, bero = None, bc = None )

Implemented in Python.

Input

f Image Gray-scale (uint8 or uint16) or binary image.
bero Structuring Element

(erosion).

Default: None (3x3 elementary cross)

bc Structuring Element

(connectivity).

Default: None (3x3 elementary cross)

Output

y Image

(same type of f).

Description

mmopenrec creates the image y by an inf-reconstruction of the image f from its erosion by bero, using the connectivity defined by Bc.

Equation

Limitations

Binary image:

Source Code

def mmopenrec(f, bero=None, bc=None):
    if bero is None: bero = mmsecross()
    if bc is None: bc = mmsecross()
    y = mminfrec(mmero(f,bero),f,bc)
    return y
