[Insight-users] Demons registration And Mutual Informations

[Luis Ibanez]

Hi Remi,

In the current form you cannot use Mutual Information
along with the Demons deformable registration.

However, relatively small modifications to the current
class could be enough for replacing its current metric
(Mean Squared Differences) with Mutual Information.

The HistogramMatchingImageFilter is not an Image Metric,
and it cannot be replaced with MutualInformation.
The Purpose of the HistogramMatching filter is to
bring the histograms to a point where they are similar
enough for using optical flow as a driving force for
the Demons.


     Regards,


        Luis
