[Insight-users] How to compute the correct center of image?

[Luis Ibanez]

Hi Zhao,

Please look at the code of

          Insight/Code/Common
             itkCenteredTransformInitializer.txx


in lines 95 to 153,
it shows how to compute the physical coordinates
of the center of an image.


Your current code is not covering all cases.


      Regards,


             Luis
