Salient object detection based on deep learning has become one of the research hotspots in computer vision. How to effectively extract useful information is a key issue for saliency detection. Most of the existing methods integrate features extracted from convolutional neural networks indiscriminately. However, the features of different layers have different characteristics, not all of them are useful for saliency detection and some even cause interferences. To solve above problem, we propose a Multi-style Attention Fusion Network (MAFNet). Specifically, MAFNet is mainly consists of dual-cues spatial attention module (DSA), dual attention intermediate representation module (DAIR), high-level channel attention module (HCA) and multi-level feature fusion module (MLFF). Among them, DSA aims to refine lowlevel features and filter background noise. DAIR uses two branches to adaptively integrate the spatial and semantic information of middle-level features. HCA obtains the semantic features of high-level blocks through two different channel-wise operations. Besides, MLFF effectively integrates the above multilevel features in a learnable manner. Finally, different from cross-entropy, cross-IOU loss guides the network to pay more attention to local details. Experimental results on six public datasets demonstrate that MAFNet's outperformance is competitive in saliency detection and performs well on small object detection. (c) 2020 Elsevier B.V.
