METHOD AND SYSTEM FOR REGISTRATION/ALIGNMENT OF 3D DIGITAL MODELS

Systems and methods, devices and software are described for use in image comparison such as required for medical planning such as in dental implantology or other applications that require registration of digital images. A method and system is described for automatically finding correspondences between two or more digital representations such as images of one or more 3D objects with an identical, partially identical or similar geometry. The method and system, devices and software have the advantage that although the different digital representations of the object may be influenced by either noise, or scatter, or occlusion, or clutter, or any combination of these, correspondence can be found.
