Abstract
We propose a novel post-production facial performance relighting system
for human actors. Our system uses just a dataset of view-dependent
facial appearances with a neutral expression, captured for a static
subject using a Light Stage apparatus. For the actual performance,
however, a potentially different actor is captured under known, but
static, illumination. During post-production, the reflectance field of
the reference dataset actor is transferred onto the dynamic performance,
enabling image-based relighting of the entire sequence. Our approach
makes post-production relighting more practical and could easily be
incorporated in a traditional production pipeline since it does not
require additional hardware during principal photography. Additionally,
we show that our system is suitable for real-time post-production
illumination editing.
