[Insight-users] Example ImageRegistration8

[ines cabezas rivas]

Hi all. I used the imageregistration8.cxx like the guide to work with 3D model images.
But I used the affine transform, the mean squares metric, the regular step gradient optimizer and the lineal interpolator. I tested the program and I used a serie like fixed image and the same serie out of place 26 pixels in axis X and Y, so the results must be similar to the displacement used, but the results are very diferents. The translation obtained is similat to [0.1,0.27,-0.34] -GetLastTransformParameters()- In the mean squares, i don´t configure the parameters. The parameters that I configured are in the optimizer:
maximumStepLenght = 0.5;
minimumStepLenght = 1E-5;
noIterations = 50.0;
relaxionFactor = 0.8; 

Does anyone have a idea, please?
Thaks you..
Best Regards!!
