Hi Vijaya,

Fixed parameters are not optimized when a transform is used in image

registration. Center of rotation is usually the fixedparameter. That is the

case with Euler

<https://itk.org/Doxygen/html/classitk_1_1Euler3DTransform.html>, Quat

<https://itk.org/Doxygen/html/classitk_1_1QuaternionRigidTransform.html> and

Versor

<https://itk.org/Doxygen/html/classitk_1_1VersorRigid3DTransform.html> rigid

3D transforms. More transform types are listed here

<https://itk.org/Doxygen/html/group__ITKTransform.html>. This example

<https://itk.org/ITKExamples/src/Filtering/ImageGrid/ResampleAnImage/Documentation.html>,

and this example

<https://itk.org/Wiki/ITK/Examples/SimpleOperations/TranslationTransform> might

help you about how to set parameters and use a transform.

Regards,

DÅŸenan

Hi

Before asking this question I searched the whole archive. I am new here.

I would like to resample an MRI image after applying 3D rigid transform

(Rotation followed by translation). I found euler3dtransform and

quaternion3d. The documentation is not suffice to see how to use it

completely. What are parameters and fixed parameters. How to give suppose

three angles a, b, c and 3 transtalations x ,y, z to these functions.

Please help me.

Thank you so much in advance,
