Applications and specificities of synthetic/synthetic projective registration

A recent application related to 3D watermarking has led to a specific registration problem: the registration of a 3D computer object with a computer-generated 2D view of it. So far, projective registration algorithms have focused on images of real objects because there was no interest in registering synthetic images with computer models. While those algorithms could also be directly applied to the case of synthetic images, they do not take advantage of some specificities of the synthetic/synthetic registration problem. This problem is addressed here and a dedicated registration algorithm is presented.
