Foreground Detection and Segmentation in RGB-D Images

Depth information available in RGB-D images facilitate many computer vision tasks. As a newly emerging and significant topic in the computer vision community, foreground detection and segmentation for RGB-D images have gained a lot of research interest in the past years. In this chapter, an overview of some foreground-based tasks in RGB-D images is provided, including saliency detection, co-saliency detection, foreground segmentation, and co-segmentation. We aim at providing comprehensive literature of the introduction, summaries, and challenges in these areas. We expect this review to be beneficial to the researchers in this field and hopefully, encourage more future works in this direction.
