The error is very clear it cannot find the file, probably you executed the MEX command from a different folder ?

Otherwise try "mex -setup" to reset your compiler settings.

I uploaded a new version with derivative boundary check bug fixed, probably tomorrow online. thnx Elmar.

Thank you for sharing the solution for your NaN problem.
Now, I know it's probably caused by a boundary check problem.

* Elmar,

Thank you for your report, I never experienced NaN's my self.
Maybe you can add a small value to rule out division by zero.

If you still have problems, maybe you can share a part of the volume data with me?

Thanx, Dirk-Jan

*James Ford,

Thank you, for the comments.

I've made some improvements, fixed the bugs you pointed out and tested the code in Ubuntu, new version is probably online tomorow.

Thank u. It realy helps me a lot!
06 Nov 2009 non-rigid b-spline grid image registration Registration of two 2D/3D images, rigid and with smooth b-spline grid. Author: Dirk-Jan Kroon Hui

Hi, Dirk,

Thanks for sharing the excellent codes.
I have two questions about your version18e codes:

1. In image_difference.m, line 34, if(exist('type','var')==0), type='p'; end. should here type = 'd' as default? Because there is no type 'p'

2. In example_2d_affine.m, can you explain a little bit about why the scale = [1 1 1 0.1 0.1] needed here? I didn't figure out the purpose of scale here.

Thanks very much.

Hui
04 Nov 2009 Bias Field Corrected Fuzzy C-Means Estimates the illumination artifact in 2D (color) and 3D CT and MRI and segments into classes. Author: Dirk-Jan Kroon ccccccc, ciaiaia

uhm in this folder D:\bin there are
mex.pl and BCFCM2D.c and many files [all files of this application *.m, *.c]
and mexutils.pm and mexsetup.pm ecc and many .bat for example [matlab]

why it doesnt find 'BCFCM2D.c' file? there is it in folder :/

Otherwise I try mex-setup but at the end there is the same the error
