Deep-learning based salient object detection methods achieve great progress.
However, the variable scale and unknown category of salient objects are great
challenges all the time. These are closely related to the utilization of
multi-level and multi-scale features. In this paper, we propose the aggregate
interaction modules to integrate the features from adjacent levels, in which
less noise is introduced because of only using small up-/down-sampling rates.
To obtain more efficient multi-scale features from the integrated features, the
self-interaction modules are embedded in each decoder unit. Besides, the class
imbalance issue caused by the scale variation weakens the effect of the binary
cross entropy loss and results in the spatial inconsistency of the predictions.
Therefore, we exploit the consistency-enhanced loss to highlight the
fore-/back-ground difference and preserve the intra-class consistency.
Experimental results on five benchmark datasets demonstrate that the proposed
method without any post-processing performs favorably against 23
state-of-the-art approaches. The source code will be publicly available at

本研究提出了 “aggregate interaction modules” 和 “self-interaction modules” 等方法来处理深度学习中显著目标检测中存在的变量规模和未知类别等挑战，同时，使用 “consistency-enhanced loss” 方法来处理由于尺度变化导致的类别失衡问题，从而提升对前 / 背景差异的识别和类内一致性的维持。实验结果在五个基准数据集上表明，该方法无需后处理即可比 23 种最先进的方法表现优异。
