16 Feb 2012 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, Many thanks for this submission. I am trying to transform a volume using a Rigid matrix as following

m=[ 0.9956 0.0491 0.0800 -10.8112
-0.0472 0.9986 -0.0256 6.8496
-0.0812 0.0217 0.9965 6.9082
0 0 0 1.0000];
he output seems screwed as expected, however, the size of the input matrix has changed drastically. That does not seems quite right. Could you kindly suggest.

Many Thanks

18 Nov 2011 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

Dear Dirk, I want to know if this algo can register a 2d image to a 3d Volume? According to my limited understanding, such registrations are done using projection based methods.. Any suggestion on this. Many thanks.
