Recently there has been remarkable success in pushing the state of the art in salient object detection. Most of the improvements are driven by employing end-to-end deeper feed-forward networks. However, in many cases precisely detecting salient regions requires representation of fine details. Combining high-level and low-level features using skip connections is a strategy that has been proposed, but sometimes fails to select the right contextual features. To overcome this limitation, we propose an end-toend encoder-decoder network that employs recurrent refinement to generate a saliency map in a coarse-to-fine fashion by incorporating finer details in the detection framework. The proposed approach makes use of refinement units within each stage of the decoder
that are responsible for refining the saliency map produced by earlier layers by learning context-aware features. Experimental results on several challenging saliency detection benchmarks validate the effectiveness of our proposed architecture providing a significant improvement over current state-of-the-art methods.
