[Insight-users] Still having problems with Refactoring Statistic classes !!

[Ricardo Ferrari]

Hi itk-users,

Previously (Digest Vol 68, Issue 109), I reported a problem I was having
with the itk::Statistics::CovarianceSampleFilter. Although, I have not got
any feedback on that issue and I could not figure it out by myself, I have
overcome the problem by writing my own function to compute the covariance
matrix.

Now, I have faced another issue when using the
itk::Statistics::GaussianMixtureModelComponent  and the
itk::Statistics::ExpectationMaximizationMixtureModelEstimator

Attached I am sending a minimal code to illustrate the problem. For testing
the code, I have downloaded two minc images (t1 and a t2 contrasts) from the
brainweb projects and converted them to dicom.

The program call and the result are presented bellow

ferrari at ferrari-workstation:~/Desktop/Test$ bin/test
t1_icbm_normal_1mm_pn3_rf20.dcm t2_icbm_normal_1mm_pn3_rf20.dcm
1
1a
1b
Segmentation fault
ferrari at ferrari-workstation:~/Desktop/Test$


Again, I really appreciate any help on clarifying these issues.  Am I using
the itk::Statistics::ImageToListSampleAdaptor class appropriately ?


Thank you very much,
Ricardo
