abstract = "Image-based Relighting (IBRL) has recently attracted
a lot of research interest for its ability to relight real
objects or scenes, from novel illuminations captured
in natural/synthetic environments. Complex lighting
effects such as subsurface scattering, interreflection,
shadowing, mesostructural self-occlusion, refraction
and other relevant phenomena can be generated using
IBRL. The main advantage of image-based graphics is
that the rendering time is independent of scene complexity
as the rendering is actually a process of manipulating
image pixels, instead of simulating light transport.
The goal of this paper is to provide a complete
and systematic overview of the research in Imagebased
Relighting. We observe that essentially all IBRL techniques
can be broadly classified into three categories
(Fig. 9), based on how the scene/illumination information
is captured: Reflectance function-based, Basis
function-based and Plenoptic function-based. We discuss
the characteristics of each of these categories and
their representative methods. We also discuss about
the sampling density and types of light source(s),
relevant issues of IBRL."
