The majority of existing methods for saliency detection based on low-level features failed to uniformly highlight the salient-object regions. In order to improve the accuracy and consistency of generated saliency maps, we propose a novel and efficient framework by combining low-level saliency priors and local similarity cues for image saliency detection. Firstly, we construct a multiple low-level prior map using location prior, color prior and background prior. Then, the prior maps employ a propagation mechanism based on Cellular Automata to enforce relevance of similar regions as a local similarity cue. Finally, a principle refinement framework by integrating multi-level prior maps and local similarity cue map are used to obtain an ultimate high-quality saliency map. Extensive experiments on publicly available datasets show that our designed approach is capable of producing accurate saliency maps compared with those generated results by the state-of-the-art saliency-detection methods.
