[Insight-users] How to compare deviation beween deformations vector field.

[bui Toan]

Dear Sir,

I have a problem about deformation field. I try to implement Demons Algorithm in Medical Image Processing. I use B-Splines transformation to get Deformation vector field of first transformation image and second transformation image. Afterthat, I will iterate B-Spline transformation step until no significant change in the deformation vector field. So, I must calculate difference (deviation) between previous deformation vector field and pos- deformation vetor field to converge. How to compare deviation beween deformations vector field.
 
Best Regards,
Bui Toan
