03 Jun 2009 B-spline Grid, Image and Point based Registration B-spline registration of two 2D / 3D images or corrsp. points, affine and with smooth b-spline grid. Author: Dirk-Jan Kroon

Hi
I'm sorry for all these questions, but I encountered another problem - I tried to run the example_nonrigid_3d example and got the following output:
Iteration Func-count Grad-count f(x) Step-size
0 1 1 0.048856
1 4 2 0.0488542 5
2 7 3 0.0488539 1
3 10 4 0.0488535 1
4 13 5 0.0488532 1
Optimizer Results
Algorithm Used: limited memory BFGS (L-BFGS)

Error in ==> refine_grid at 111
O_new=O_new(1:size(X,1),1:size(X,2),1:size(X,3),1:3);

Error in ==> example_3d_nonrigid at 51
[O_trans,Spacing]=refine_grid(O_trans,Spacing,size(I1));

Do I need to change any params?
Thanks again,
Aya

It worked - thanks!
Is there help somewhere? or should I use the examples?

Hi
I encountered a compilation problem, which seems different than the ones already posted:

Writing library for bspline_transform_3d_single.mexw32
c:\docume~1\admini~1\locals~1\temp\mex_vrmztx\bspline_transform_3d_single.obj .text: undefined reference to '_floorf'

C:\PROGRA~1\MATLAB\R2008A\BIN\MEX.PL: Error: Link of 'bspline_transform_3d_single.mexw32' failed.

I'm using matlab 2008a

Thanks!
Aya
