A new imaging technique will let you select an item in a photo — from a small chair to a large taxi — convert it into 3D, and reposition it in the original image as desired.
Developed at Carnegie Mellon and the University of California, the technique taps into libraries of stock 3D models. You simply alter the model to better fit the image, and then viola!: more photo manipulation than you otherwise thought possible.
“We present a method that enables users to perform the full range of 3D manipulations, including scaling, rotation, translation, and nonrigid deformations, to an object in a photograph,” the researchers say. Also, “as 3D manipulations often reveal parts of the object that are hidden in the original photograph, our approach uses publicly available 3D models to guide the completion of the geometry and appearance of the revealed areas of the object.”
