3D Landmarks #8

Open RarimanRochaMS opened 4 months ago

RarimanRochaMS commented 4 months ago

Hello,

If I only have the 3D landmarks of the target, is it possible to fit the template to these landmarks?

Thanks,

NaughtyZZ commented 4 months ago

The corresponding landmarks of the template is required to annotate only once for all targets.

Thanks for your prompt reply.

I wasn't clear enough. For the target, I do not have the mesh (.ply), but I only have the 3D landmarks. I would like to fit the template to 3D landmarks of the target, without knowing the target mesh.

I think it is also OK. In the E-M registration process, the offset for closest-vertex-correspondence should be eliminated if you do not have the target surface. You can try it.
