[Insight-users] Interesting Blob

[Luis Ibanez]

Hi Kevin,

Yes, blob spatial objects can be treated like images.

In particular if you plan to create a mask with them.

We use spatial objects as masks for registration.


Using Blobs you can create a mask similar to the one
in your post by setting two positive blobs and a negative
one of smaller radius and larger peak value.

Note that for visualization purposes, SpatialObject can
be resampled into images using the SpatialObjectToImageFilter:

    Regards,
