Another Cool Image Processing Technique

This one allows you to change the object's material type in your photos. Now you can make your ceramic vase looks dull, translucent, or metallic, etc.

From the paper's description:

Here we present a method for automatically replacing one material with another, completely different material, starting with only a single high dynamic range image as input. Our approach exploits the fact that human vision is surprisingly tolerant of certain (sometimes enormous) physical inaccuracies, while being sensitive to others. By adjusting our simulations to be careful about those aspects to which the human visual system is sensitive, we are for the first time able to demonstrate significant material changes on the basis of a single photograph as input.
