Abstract
Abstract A method of processing an image of a three-dimensional object, including the steps of providing a morphable object model derived from a plurality of 3D images, matching the morphable object model to at least one 2D object image, and providing the matched morphable object model as a 3D representation of the object. A method of generating a morphable object model includes the steps of generating a 3D database comprising a plurality of 3D images of prototype objects, subjecting the data of the 3D database to a data processing providing correspondences between the prototype objects and at least one reference object, and providing the morphable object model as a set of objects comprising linear combinations of the shapes and textures of the prototype objects.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
115 words
A method of processing an image of a three-dimensional object comprising: providing a morphable object model derived from a plurality of 3D images, said morphable object model being a multidimensional 3D morphing function comprising coefficients that are image attributes of said object; matching the morphable object model to at least one 2D object image to obtain a matched object model, said matching comprising a non-linear optimization of said coefficients on the basis of parameters comprising orientation of said object and illumination conditions; subjecting the matched object model to a back-projection to color data of the 2D input image of the object; and providing the matched morphable object model as a 3D representation of the object.
Claim 2
Independent Claim
115 words
A method of processing an image of a three-dimensional object comprising: providing a morphable object model derived from a plurality of 3D images, said morphable object model being a multidimensional 3D morphing function comprising coefficients that are image attributes of said object; matching the morphable object model to at least one 2D object image to obtain a matched object model, said matching comprising a non-linear optimization of said coefficients on the basis of parameters comprising orientation of said object and illumination conditions; subjecting the matched object model to a back-projection to color data of the 2D input image of the object; and providing the matched morphable object model as a 3D representation of the object.
Claim 3
Dependent Claim
26 words
The method according to claim 1 , wherein the matched morphable object model is subjected to a modelling step to modify at least one object feature.
Claim 4
Dependent Claim
28 words
The method according to claim 1 , wherein the objects are selected from the group consisting of human faces, animal faces, human bodies, animal bodies and technical objects.
Claim 5
Dependent Claim
26 words
A method of recognizing an object, wherein a 3D model of the object to be recognized is processed with a method according to claim 1 .
Claim 6
Dependent Claim
22 words
A method of synthesizing a 3D model of a face with certain facial attributes with the method according to claim 1 .
Claim 7
Independent Claim
90 words
A method of processing an image of a three-dimensional object comprising: providing a morphable object model derived from a plurality of 3D images; matching the morphable object model to at least one 2D object image to obtain a matched object model; subjecting the matched object model to a back-projection to color data of the 2D input image of the object, wherein the back-projection yields an illumination correction for obtaining color data of a surface of the object providing the matched morphable object model as a 3D representation of the object.
Claim 8
Independent Claim
90 words
A method of processing an image of a three-dimensional object comprising: providing a morphable object model derived from a plurality of 3D images; matching the morphable object model to at least one 2D object image to obtain a matched object model; subjecting the matched object model to a back-projection to color data of the 2D input image of the object, wherein the back-projection yields an illumination correction for obtaining color data of a surface of the object providing the matched morphable object model as a 3D representation of the object.
Claim 9
Dependent Claim
15 words
The method according to claim 6 , wherein the color corrected data are subjected to
