Great! It works! thank you Gaëtan :)
But i got an error when i tried to use ITK python to finish some
Registration work....Here is my code:
transformer = itk.TranslationTransform[itk.D, 3].New()
optimizer = itk.RegularStepGradientDescentOptimizer.New()
interpolator = itk.LinearInterpolateImageFunction[itk.Image.US3,
itk.D].New()
metric =
itk.MeanSquaresImageToImageMetric[itk.Image.US3,itk.Image.US3].New()
registration_object =
itk.ImageRegistrationMethod[itk.Image.US3,itk.Image.US3].New()
registration_object.SetMetric(metric)
~~~~~~~~~~~~~~~~~~~~~~~~~~~ I got an error from this
TypeError: Type error. Got
_p_itk__SmartPointerTitk__MeanSquaresImageToImageMetricTitk__ImageTunsigned_short_3u_t_itk__ImageTunsigned_short_3u_t_t_t,
expected
_p_itk__SmartPointerTitk__ImageToImageMetricTitk__ImageTunsigned_short_3u_t_itk__ImageTunsigned_short_3u_t_t_t
Is there something i do wrong when invorking the method? The error may
indicate the SetMetric function requires a base class... could you tell how
to solve it.... many many thanks
