[Insight-users] Problem with itkLandmarkBasedTransformInitializer

[Siwei Yang]

Dear all,
I found, that itkLandmarkBasedTransformInitializer can not deal with 
such a situation(our transform is CenteredRigid2DTransform), where the  
angel between two fixed landmars and two moving landmarks is greater 
than 90 degree. e.g 160 degree.
I think, it might be due to it ---In the 
itkLandmarkBasedTransformInitializer.txx line 384 , "if( s_dot > 0.00005 
)......."
I 'm not sure, if we should rewrite it just like "if ( fabs(s_dot) > 
0.00005 )...". At least it can run successfully for the case above.

best wishes
Siwei Yang
