[mmhmin] [Up] [mmhmax] | Connected Operators |
Implemented in Python.
f | Image Gray-scale (uint8 or uint16) image. |
v | Double Volume parameter. Default:
|
Bc | Structuring Element Structuring element (connectivity). Default:
|
y | Image Gray-scale (uint8 or uint16) or binary image. |
mmvmax This operator removes connected domes with volume less than
v
. This function is very similar to
mmhmax, but instead of using a gray scale criterion (contrast) for the dome, it uses a volume criterion.
>>> a = uint8([ [4, 3, 6, 1, 3, 5, 2], [2, 9, 6, 1, 6, 7, 3], [8, 9, 3, 2, 4, 9, 4], [3, 1, 2, 1, 2, 4, 2]])
>>> print mmvmax(a,10,mmsebox())
[[4 3 6 1 3 5 2] [2 6 6 1 5 5 3] [6 6 3 2 4 5 4] [3 1 2 1 2 4 2]]
>>> f = mmreadgray('astablet.tif')
>>> mmshow(f)
>>> fb = mmvmax(f,80000)
>>> mmshow(fb)
>>> mmshow(mmregmax(fb))

def mmvmax(f, v=1, Bc=None): if Bc is None: Bc = mmsecross() print 'Not implemented yet' return None return y
mmsebox | Create a box structuring element. |
mmsecross | Diamond structuring element and elementary 3x3 cross. |
mmfreedom | Control automatic data type conversion. |
