Exploiting Surroundedness and Superpixel cues for salient region detection

In this paper, we will present a new salient region detection method by exploiting its surrounding and superpixel cues. Its main highlights are: 1) An input image is quantized to 256 colors by using minimum variance quantization; 2) Saliency maps is computed based on the figure-ground segregation of the quantized image; 3) Mean saliency value of each superpixel is employed to refine saliency maps further. This can highlight salient objects robustly and suppress backgrounds evenly. Experimental results show that the proposed method produces more accurate saliency maps and performs well against twenty-one saliency models concerning three evaluation metrics on two public datasets.
