[Insight-users] help itkImageGaussianModelEstimator

[adusumilli samatha]

Hello sir/madam

I have tried to execute the example GibbsPriorFilter1
from itk examples.I have supplied the "input image"
and "training image"(drawn an ROI and filled it with
intensity 1 and then saved it as Training image).I am
attaching those images.
When i run this program i am getting an exception at
try
{
	applyEstimateModel->Update(); ***
}
catch(itk::ExceptionObject &exp)
{
	std::cerr<<"Exception caught"<<std::endl;
	std::cerr<<exp<<std::endl;
}	
and the ouput i am getting is

Gibbs Prior Test Begins:
Exception caught

Please guide me where it has gone wrong.
I am not clear what is "Training image" and how to
create it.

Thanks
