1. A method of identifying a multifeatured object corresponding to at least one source 2D projection of a source multifeatured object, the method comprising the steps of: a. providing a plurality of 3D representations of candidate multifeatured objects; b. detecting the source 2D projection in an image; c. performing a viewpoint-invariant search of the candidate 3D representations to locate the candidate 3D representation having a 2D projection most resembling the at least one source 2D projection; and d. comparing the at least one source 2D projection with the candidate 3D representation located in step c. to determine whether the candidate corresponds to the source.
