mmcloserec
Closing by reconstruction.

Synopsis

y = mmcloserec( 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)

bc Structuring Element

( connectivity).

Default: None (3x3 elementary cross)

Output

y Image

Same type of f.

Description

mmcloserec creates the image y by a sup-reconstruction ( with the connectivity defined by the structuring element bc) of the image f from its dilation by bdil.

Examples

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

              
>>> mmshow(a)

              

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

              

              
>>> mmshow(b)
