[Insight-users] Registration

[nedunuri ramakrishna]

Dear Mr.Luis,

I am working on registration.
	I could trace the registration process using the
"itkcommand.h".
My moving image is generated from fixed image by
rotating in 2 degrees.

Optimizer parameters are:
 optimizer->SetNumberOfIterations(   1000   );
 optimizerScales[0] = 1.0; // scale for M11
 optimizerScales[1] = 1.0; // scale for M12
 optimizerScales[2] = 1.0; // scale for M21
 optimizerScales[3] = 1.0; // scale for M22
 optimizerScales[4] = 1.0  // scale for translation on
Y
 optimizerScales[5] = 1.0  // scale for translation on
Z

When i displayed the iterations  of the optimizer
using optimizer->GetCurrentIteration(),i observed that
registration process is stopping at '7'
iteration.After 7 th iteration regisrtation process
stopped and matrix is diaplayed.
I could not get the expected output.
I think Sin(2) means,I should get the  0.03489 in the
rotation matrix.
But,I am getting
Metric value: -0.934061

1.0002, -0.00145522, -0.00155741, 0.999049

translation in X: 2.76434
translation in y: -8.34538

My dataaset is of size 256X256X1.
Affinetransfrom gave only 6 parameters.

Please suggest me why it is happening so.What should i
do to get the expected output.

Thanks in advance,

Regards,
Ramakrishna.
