abstract = "This paper addresses the problem of foreground extraction using
active illumination and graph-cut optimization. Our approach
starts by detecting image regions that are likely to belong to
foreground objects. These regions are constituted by pixels where
the difference in luminance for two differently illuminated images
is large. The foreground objects are segmented by graph-cut
optimization using those regions as a seed and using a energy
function based on probability distributions derived from both
input images and their difference. Several light sources and
different illumination schemes can be used to mark the foreground.
Our method has only two scalar parameters which can be set once
for a wide variety of scenes.",
