Dear Daniel,
thanks for the information about the visualization errors. You can
download my test Datasets (actually its the same dataset twice just
slightly moved in z-direction) from our FTP server.
ftp://ftp.igd.fraunhofer.de/outgoing/makeil/
I saved them in .pic format so that you can read them.
Best regards,
Matthias

Dear Matthias,
sorry for the delay, but I was out of office and since I have implemented the
module so far no one else has answered you. I have applied your patch to my
working solution today. The manual registration sliders are working fine with
your patch, so I will commit it tomorrow. I will let you know the SVN revision
containing your patch.
Thank you very much for contributing the patch!
Regarding your other problem, we are currently working on some issues with the
correct visualization for every update during registration within MITK. Maybe
you can send me your testcase images, so that I can check them as well and can
try to find a solution.
Best regards,
Daniel

Betreff: Re: [mitk-users] Visualization Error after Registration
Dear MITK developers,
it would be nice if you could give me a little update about the status
of my patch. Unfortunately I didn't get any feedback so far.
Best regards,
Matthias

Dear MITK developers,
I am working quite a lot with the QmitkRigidRegistration widget. I was
playing around a bit with the different metrics and optimizers
included in the functionality. I did so by decomposing a given
translation into its x, y and z component. Registration worked out
quite well for these easy given tasks (translating by 2 mm along each
axis).
Unfortunately there seems to be an error in displaying the
registration results and optimization steps. I attached a .zip file to
visualize this error. The calculations done for the registration are
correct, as you can see from the output windows (amount of translation
is exact and mean squares metric has value 0). The error that occurs
is that a translation in x direction results in a translation in z
direction in the visualization and vice versa.
I think that the error must be somewhere in the following function:
QmitkRigidRegistrationSelector::SetOptimizerValue
which is called for each optimizer step. I do not think that this
error is limited to the translation transform case only, but is more
systematically. Therefore I think that something might be wrong in the
last part of the function, where the m_movingGeometry member is
calculated.
Unfortunately I am not that experienced with the given transformations
and changes between ITK and VTK yet.
I am looking forward to hearing from you!
Best wishes,
Matthias Keil
