[Insight-users] Using MultiResolutionPyramidImageFilter : Exception occurred during SingleMethodExecute - please help

[Luis Ibanez]

Hi Kastern,

Your code seems to be fine...


A couple of questions:

   1) What is the size (in pixels) of your input image ?
   2) What is the pixel spacing of your input image ?



Please let us know,


    Thanks


      Luis
