Future Macs -- and perhaps iOS devices -- may sport 3D object recognition. An Apple patent (number 20120114251) for a method, device, system, and computer program for object recognition of a 3D object of a certain object class using a statistical shape model for recovering 3D shapes from a 2D representation of the 3D object and comparing the recovered 3D shape with known 3D to 2D representations of at least one object of the object class has appeared at the U.S. Patent & Trademark Office.
Here's Apple's background and summary of the invention: "The present invention relates to automated object recognition and in particular to automated object recognition of 3D objects using statistical shape information.
