Hi,<br>
I'll try to use the tecniques you suggetsted me.<br>
Do these tecniques return a vector field as the fem-based and do they work also on 3D images, as the volumes I appended?<br>

hi<br><br>is there a special reason why you insist on fem based registration?<br><br>there are other techniques in itk:<br>- demons based registration in case you can assume brightness constancy<br>- MI based bspline registration in case your image intensities differ
<br>between images<br><br>both techniques lead to good results if you implement them in a<br>multi-resolution manner, and they are more straightforward to use than<br>the FEM framework<br><br>on your 2d images they should also be reasonably fast!

<br>><br>><br>> Hi,<br>> I' ve a doubt about Deformable Registration.<br>> It's 2 weeks I'm trying to tune the parameters of fem-based deformable<br>> registration in order to match the image Differenza_t02.vtk to
<br>> Differenza_t01.vtk but it's totally usefull.<br>> So I'm asking if it's possible to obtain a good matching between these 2<br>> images, and so a good vector field which leads me to image _t01 from<br>> _t02, or if I'm totally wrong in using this tecnique.
<br>> I'm asking you: can I use the DeformableRegistration1 in order to<br>> transport the cells in image 02 in the positions they have in image 01?<br>><br>> Please help me, I could have wasted about 100 hours of work.
<br>><br>> I've appended the URL's of the two volumes I've to match: these are 2<br>> successive frames obtained with confocal microscopy.<br>><br></blockquote></div><br>
