A novel graph structure for salient object detection based on divergence background and compact foreground

no code implementations30 Nov 2017 Chenxing Xia, Hanling Zhang, Keqin Li

Different from prior methods, we calculate the saliency value of each node based on the relationship between the corresponding node and the virtual node.
