mmcloserecth
Close-by-Reconstruction Top-Hat.

Synopsis

y = mmcloserecth( f, bdil = None, bc = None )

Implemented in Python.

Input

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

bdil

Structuring Element

(dilation)

Default: None (3x3 elementary cross)

Structuring Element

( connectivity)

Default: None (3x3 elementary cross)

Output

y	Image Gray-scale (uint8 or uint16) or binary image.

Description

mmcloserecth creates the image y by subtracting the image f of its closing by reconstruction, defined by the structuring elements bc and bdil.

Examples

>>> a = mmreadgray('danaus.tif')

>>> mmshow(a)

>>> b = mmcloserecth(a,mmsebox(4))

>>> mmshow(b)


a	b
