摘要：In this paper, we propose a visual saliency detection algorithm which incorporates both generative and discriminative saliency models into a unified framework First, we develop a generative model by defining image saliency as the sparse coding residual based on a learned background dictionary. Second, we introduce a discriminative model by solving an optimization problem
that exploits the intrinsic relevance of similar regions for regressing region-based saliency to the smooth state.Third, a weighted sum of multi-scale region-level saliency is computed as the pixel-level saliency, which genera
