Bi-layer video segmentation with foreground and background infrared illumination
Qiong Wu, Pierre Boulanger, Walter F. Bischof · 2008
In this paper, we investigate two ways of employing infrared video with color video for automatic foreground-background video segmentation: foreground infrared (IR) illumination and background IR illumination. Foreground IR illumination gives an initial foreground template, which is combined with image segmentation to complete foreground segmentation. Two algorithms are explored, Graph Cut and Relaxation Labeling. The disadvantage of foreground IR illumination can be compensated by background illumination.
