                         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.",
