mmopenth
Opening Top Hat.

Synopsis

y = mmopenth( f, b = None )

Implemented in Python.

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

structuring element

Default: None (3x3 elementary cross)

y	Image Gray-scale (uint8 or uint16) or binary image. (same type of `f`).

mmopenth creates the image y by subtracting the morphological opening of f by the structuring element b of f itself.

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

>>> mmshow(a)

>>> b = mmopenth(a,mmsebox(3))

>>> mmshow(b)


a	b
