Salient Object Detection via Augmented Hypotheses

In this paper, we propose using augmented hypotheses which consider objectness, foreground and compactness for salient object detection. Our algorithm consists of four basic steps. First, our method generates the objectness map via objectness hypotheses. Based on the objectness map, we estimate the foreground margin and compute the corresponding foreground map which prefers the foreground objects. From the objectness map and the foreground map, the compactness map is formed to favor the compact objects. We then derive a saliency measure that produces a pixelaccurate saliency map which uniformly covers the objects of interest and consistently separates foreand background. We finally evaluate the proposed framework on two challenging datasets, MSRA1000 and iCoSeg. Our extensive experimental results show that our method outperforms state-ofthe-art approaches.
