[Insight-users] 2D rigid registration problems

[Luis Ibanez]

Hi Auron,


                       Welcome to ITK !


In order to help  you with the registration problem that you are facing,
we will need to know more about the images that you are registering.


   a) Can you post a couple of your PNG images in a public web site ?

        * Are your images in grayscale ? color ?
        * What is the size in pixels ?
        * What kind of transformations do you anticipate between them ?
          (rotation ? translation ? scaling ?)

   b) Can you post to the list the output of the command observers ?
      (e.g. the values of the metric and transform parameters at
      every iteration of the optimizer).



Probably the best way to start is by posting a coupld or example
images in a public web site.



    Regards,


       Luis
