[Insight-users] Problem with Rigid Registration Mattes-MI and FixedImageMask

[Serena Fabbri]

Hi All,

I am registering MRI and CT image with Rigid Registration and Mattes MI.
I use a mask for the fixed image (MRI) but I get this error:

ExceptionObject caught !

itk::ExceptionObject (0x1006b07c0)
Location: "void itk::MattesMutualInformationImageToImageMetric<TFixedImage, 
TMovingImage>::GetValueAndDerivative(const typename itk::ImageToImageMetric<TFixedImage,

TMovingImage>::MeasureType&, typename itk::ImageToImageMetric<TFixedImage, 
TMovingImage>::DerivativeType&) const [with TFixedImage = itk::Image<float, 3u>, TMovingImage =

Err in Reg blocco


any ideas?


Thank you very much.
