Taking a Deeper Look at Co-Salient Object Detection

Image GT (a) (b) (c) (d) Figure 1: Different salient object detection (SOD) tasks. (a) Traditional SOD [75]. (b) Within-image co-salient object detection (CoSOD) [89], where common salient objects are detected from a single image. (c) Existing CoSOD, where salient objects are detected according to a pair [51] or a group [81] of images with similar appearances. (d) The proposed CoSOD in the wild, which requires a large amount of semantic context, making it more challenging than existing CoSOD.
