Centralized Information Interaction for Salient Object Detection
The U-shape structure has shown its advantage in salient object detection for
efficiently combining multi-scale features. However, most existing U-shape
based methods focused on improving the bottom-up and top-down pathways while
ignoring the connections between them. This paper shows that by centralizing
these connections, we can achieve the cross-scale information interaction among
them, hence obtaining semantically stronger and positionally more precise
features. To inspire the potential of the newly proposed strategy, we further
design a relative global calibration module that can simultaneously process
multi-scale inputs without spatial interpolation. Benefiting from the above
strategy and module, our proposed approach can aggregate features more
effectively while introducing only a few additional parameters. Our approach
can cooperate with various existing U-shape-based salient object detection
methods by substituting the connections between the bottom-up and top-down
pathways. Experimental results demonstrate that our proposed approach performs
favorably against the previous state-of-the-arts on five widely used benchmarks
with less computational complexity. The source code will be publicly available.Comment: V2 updates the evaluation results of all methods on the ECSSD dataset
(Table. 3 on Page. 8). In V1 we used the old version of ground-truths of
ECSSD, which were updated later by its authors. In V2 we use the updated ones
instead. Although the numerical evaluation scores of all methods on ECSSD in
V1 and V2 vary slightly, the overall trending is still the sam
