Using mid-high level cues to detect salient object

This paper proposes a novel saliency object detection method by using the mid-level and high-level visual cues. In the mid-level objectness evaluation, we generate three complementary saliency maps, such as the multi-scale segmentation cue, the background cue and the spatial color distribution cue. The first cue is used to highlight the objects via the local region segment. The second cue uses the background priors to detect the saliency information. The third cue is to capture the spatial color distribution. For the high-level visual cue, we propose an objectness evaluation model to distinguish the object and the background. All the saliency cues are finally combined to achieve the saliency detection. The experimental results show that the proposed method outperforms the state-of-the-art saliency object detection methods.
