Dear CGAL team,

I am generating 3d meshes from segmented medical images and i want to register the two of them in a second phase. However the generated mesh doesnt follow the topology of the initial image. How could I make the mesh and the image to have the same reference system? Thank you in advance.

Hi Konstantinos,

I'm not related to the CGAL team, but as I'm doing something similar, just to chip in: we do all registration to our initial coordinate system prior to using CGAL. In fact, we actually work on a mixture of surfaces, extracted from the registered images and elsewhere, so our code is not even aware of the upstream image. However, unless the CGAL team can suggest registration tools inside CGAL, you might want to look at something like ITK for the first step - I'm afraid image manipulation itself is outside my area of expertise.

With best wishes,
