[Insight-users] Extract all disconnected regions

[Rémi Blanc]

Hi,

here would be my idea:

I haven't used ConnectedComponentImageFilter, but as far as I understand 
the documentation, the output should be an image where each connected 
component has a unique label.
You could feed this image to a LabelImageToLabelMapFilter to get a 
LabelMap containing one LabelObject per connected component.
Then, for each of these LabelObject, you can
  - create a new label map (with same origin, spacing & size)
  - add the current labelObject
  - use a LabelMapToBinaryImageFilter to generate a binary image out of it.

Best,

Rémi
