Query: Co-saliency Detection for RGBD Images Based on Multi-constraint Feature
  Matching and Cross Label Propagation   Co-saliency detection aims at extracting the common salient regions from an
image group containing two or more relevant images. It is a newly emerging
topic in computer vision community. Different from the most existing
co-saliency methods focusing on RGB images, this paper proposes a novel
co-saliency detection model for RGBD images, which utilizes the depth
information to enhance identification of co-saliency. First, the intra saliency
map for each image is generated by the single image saliency model, while the
inter saliency map is calculated based on the multi-constraint feature
matching, which represents the constraint relationship among multiple images.
Then, the optimization scheme, namely Cross Label Propagation (CLP), is used to
refine the intra and inter saliency maps in a cross way. Finally, all the
original and optimized saliency maps are integrated to generate the final
co-saliency result. The proposed method introduces the depth information and
multi-constraint feature matching to improve the performance of co-saliency
detection. Moreover, the proposed method can effectively exploit any existing
single image saliency model to work well in co-saliency scenarios. Experiments
on two RGBD co-saliency datasets demonstrate the effectiveness of our proposed
model.
