[Insight-users] how to reduce the run time of ITK

[Luis Ibanez]

Hi Yixun,


We will need you to provide the following information,
in order to be able to give you any useful advice:

 1) What operating system and compiler are you using ?
 2) What specific registration algorithm did you used ?
 3) What time did it take you to register the images ?
 4) What is the size (in pixels) of your images ?


The first thing that you should try in general is to select


          CMAKE_BUILT_TYPE = Release


both when you configure ITK and when you configure your
application.


Please let us know about the registration method that you
used, since the options for speeding up are method-dependent.


  Thanks


     Luis
