Hierarchical grouping and window scoring are two important branches of region proposal. Each branch has its advantages and disadvantages. We propose a novel region proposal framework based on saliency detection to integrate their advantages. We first use salient region detection method to divide an image into salient regions and non-salient regions. In salient regions, we use hierarchical grouping method to generate proposals. On the contrary, in the nonsalient regions, we use window scoring method. At last, linear combination is employed to fuse the different scores of these two methods. Experiments show that our method achieves the superior quality to the state-of-the-arts.
