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.
Claims7
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.
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.
