[Insight-users] Spacial object as a masks to create a ROI?

[Karthik Krishnan]

There are quite a few methods:

ImageRegistrationMethod->SetFixedImageRegion()
metric->SetFixedImageMask(), SetFixedImageRegion, SetMovingImageMask()

Effectively the metric iterator iterates over each pixel in the Fixed 
image that is both the FixedImageMask and the FixedImageRegion specified 
and that also after transformation maps into the mask specified through 
the SetMovingImageMask().
