16 Apr 2009 Resampling volume or image with affine matrix Use affine matrix to convert 3D vol or 2D img to orthogonal one with corresponding affine matrix. Author: Jimmy Shen

Dear Jimmy,

Thank you for the contribution.

Translation seems buggy, at least it doesn't work at all for me. I've been using a
[ 1 0 0 dx;
 0 1 0 dy;
0 0 1 dz;
0 0 0 1;]
matrix.

The input and output volume are pretty much the same.

Regards,
Hamid
06 Nov 2008 gen_susan Filtering with intensity dependent filter kernel. Author: Bjorn Gustavsson

Dear Björn

Thank you for the implementation.

I believe there is a bug in the line 81, should be
I_internal = I([ones(1,ceil((regsize(1)-1)/2)) 1:end size(I,1)*ones(1,(regsize(1)-1)/2)],...
               [ones(1,ceil((regsize(2)-1)/2)) 1:end size(I,2)*ones(1,(regsize(2)-1)/2)]);

Cheers,
Hamid Sarve
