Hi Luca
Thanks for the reply. I tried running:
vmtkicpregistration -ifile source_surface.vtp -rfile target_surface.vtp -ofile
registered_surface.vtp -iterations 100 -maxmeandistance 0.01
And I get the following error:
Creating vmtkICPRegistration instance.
Automatic piping vmtkicpregistration
Parsing options vmtkicpregistration
vmtkicpregistration error: unknown option -iterations
vmtkicpregistration : register a surface to a reference surface using
the ICP algorithm
Input arguments:
-id Id (int,1); default=0: script id
....
I can't figure out why it will not recognize -iterations as an option. Please
let me know what you think.
Thanks
Manasi

Hi Manasi,
try with the vmtkicpregistration script. The amount of success you can have
with this filter can change according to the kind of registration you want to
perform, but at least it's a starting point:
vmtkicpregistration -ifile source_surface.vtp -rfile target_surface.vtp -ofile
registered_surface.vtp -iterations 100 -maxmeandistance 0.01
Increase the -iterations option to check that the registration has actually
converged, and use -maxmeandistance to tell the script what you mean by
"registered" (in terms of the maximum allowed mean distance between the surface
- if that value is lower than the option, the registration stops regardless of
the number iterations that are set).
There is another useful option: -farthreshold (e.g. -farthreshold 0.2) which
tells the algorithm to ignore the pair of points that are far apart more than
0.2 during the registration. It's useful for surfaces that have parts that are
similar (that you want to register) but others that differ markedly.
Hope this helps
Luca

Hi All,
Have any you registered models using vmtk? If so, can you tell me how to do it?
I have 2 3D models (.vtp/.stl/.dat/.vti) and I want to register the 2 models.
Is it possible to do that on vmtk?
Thanks
Manasi
