Hi Luis,
Thanks for ur mail.
As u said i am printing the initial transform paramters. I get the
following values:-
[1, 0, 0, 1, 70.4192, 75.7447, -188.845, -146.701]
I used "CenteredTransformInitializer" class for initializing the
CenteredAffineTransform.
Even now i get the same error from itk. I tried with different values =
for
the paremeters but the error doesn't get any affect.
Error is:-
itk::ExceptionObject (0012FD38)
Location: "Unknown"
File:
G:\NEWITKFILES\NewVersionITK7_4_2003\itksrc\Code\Algorithms\itkMattesMutu=
alI
nformati
onImageToImageMetric.txx
Line: 546
Description: itk::ERROR:
MattesMutualInformationImageToImageMetric(00302740): Too many sam
ples map outside moving image buffer: 52 / 1000
Not even one iterations are generated this time also...
What else i have to change the parameters...
Any estimate of suitable parameters...
My data sets are 512x512x1 (0.976562/0.976562 spacing) and 128x128x1
(3.906250/3.906250 spacing). Image type is short.
Please suggest me...
Thanks in advance.
-Regards,
Sateesh.
