Free-form Textured Surfaces Registration by a Frequency Domain Technique

Free-form 3-D surfaces registration is a fundamental problem in 3-D imaging, tipically approached by extensions or variations of the ICP algorithm. This work presents a new frequency domain technique for 3-D view registration, totally diierent form an other recently proposed t e chnique for 3-D motion estimation also, based on the Fourier transform. Conceively, the proposed method c an give a non feature-based method for unsupervised registration of 3-D views. The obtained results are useful \per se" in applications targeted to visual quality or can serve as good starting point for the ICP algorithm when a higher precision is needed.
