abstract = "We present a practical solution to the problem of single-image
relighting of objects with arbitrary shapes. It is based on a
shading-ratio image obtained from some user-provided guess of the
original and target illuminations. Our approach is flexible and
robust, being applicable to objects with non-uniform albedos and
arbitrary shapes, as well as to non-photorrealistic depictions. We
demonstrate its effectiveness by relighting many photographs,
paintings, and drawings containing a variety of objects of
different materials. Additionally, our technique can transfer
smooth normal and depth maps from 3-D models to pictures.
Preliminary evaluation has shown that our approach is intuitive,
allowing novice users to relight images in just a couple of
minutes.",
