Boundary-Aware Salient Object Detection via Recurrent Two-Stream Guided Refinement Network [article]

Fangting Lin, Chao Yang, Huizhou Li, Bin Jiang
2019 arXiv   pre-print
Recent deep learning based salient object detection methods which utilize both saliency and boundary features have achieved remarkable performance.  ...  However, most of them ignore the complementarity between saliency features and boundary features, thus get worse predictions in scenes with low contrast between foreground and background.  ...  On the other hand, we also add F S i−1 to F B i to supplement missing saliency information, and use F G B i to generate more detailed boundary information.  ...
