Extracting object from an image, transforming the object (rotating, for example), re-blended it into the original image. Or making 3d game assets from objects you have around. Imagine: take your phone, go around town, into shops, into churches, come back, press a button, get huge library 3d assets to populate your game. Or, something like this, for IKEA: couple of photos of a room --> extract objects --> let user re-arrange furniture. The room could be either the user's room or an IKEA showroom. You can do it with existing tools, but this kind of technology reduces it to pressing a couple of buttons.
