Abstract In this paper, we address RGB‐D salient object detection task by jointly leveraging semantics and contour details of salient objects. We propose a novel semantics‐and‐details complementary fusion network to adaptively integrate cross‐model and multilevel features. Specifically, we employ two kinds of fusion modules in our model, which are designed for fusing high‐level semantic features and integrating contour detail features of the scene components, respectively. The semantics fusion module aggregates high‐level interdependent semantic relationships by a nonlinear weighted summation of small and medium receptive fields. Meanwhile, the details module integrates multi‐level contour detail features to leverage expressive details of salient objects. We achieve new state‐of‐the‐art salient object detection results on seven RGB‐D datasets, that is, STERE, NJU2000, LFSD, NLPR, SSD, DES, and SIP2019 dataset. Experimental results demonstrate that our method outperforms eleven state‐of‐the‐art salient object detection methods.
