[Insight-users] Registration and Spacing : Bug : Fixed

[Luis Ibanez]

The problem with the registration and image spacing
is fixed now.

The GradientRecursiveGaussian filter used in the
ImageToImageMetric takes the image spacing into
account and expect SetSigma() to be set in millimeters,
not in pixels.

The ImageToImageMetric was setting sigma to 1.0 by
default. This resulted in extreme blurrings for images
whose pixel spacing was   << 1.0.

For example, Carolyn's data with 0.00278 spacing, was
being blurred as much as an image with 1.0 spacing and
a sigma of 300.

The changes have been commited in CVS.


Please let us know if you find any further problems,


   Thanks,


     Luis
