Our Touch-n-Paste allows a user to touch one part of an object, copy and move its texture, and paste it onto another object, directly with his or her hand, in an augmented reality environment. To transfer texture appropriately from one part of an object to another, two texture images are generated by the Least Square Conformal Map (LSCM) technique. Two regions in the texture images corresponding to source and target areas of interest are then obtained using cross-boundary brushes. Target texel values are sampled from corresponding source texels by Moving Least Squares (MLS), and are finally mapped onto the target object.
