[Insight-users] problem about template a class with itkimage

[Baoyun Li]

Dear All:

I am trying to wirte some template class which is templated over itkImage with  following class defintion. At this time, I just want my code to do somework with the help of itk tools. But something is wrong with my constructor an deconstructoer although  I did not do anything using them now.

The error message shows me I should not call itkImage constructor or destructor since they are protected.  Can somebody tell me the right way to do the work.

I have listed the code and error message.

Thanks and my best regards

Baoyun

1.   The intilization of this class

     typedef ChanVese<InputImageType,InputImageType,float> ChanVeseType;
      ChanVeseType leveset1;
