Please look at the example program:
It registers two images of different modality using the
The Metric *does* consider only the overlap region between the
Fixed image and the transformed Moving image.
You can easily verify this by looking a the file
in particular to lines 69 to 102.
This use of the overlap region is, by the way, something that *all* the
ITK Image Metrics do.
Notice that in addition to that you can use the optional FixedImageMask
and MovingImageMask in order to further restrict the region that
contributes to the computation of the metric.
For examples on the use of the RegularGradientDescentOptimizer
please look at the following files:
and, of course, we *strongly* encourage you to read the Chapter on
Image Registration from the ITK Software Guide
