Saliency Detection for Unconstrained Videos Using Superpixel-Level Graph and Spatiotemporal Propagation.
IEEE Transactions on Circuits and Systems for Video Technology(2017)
摘要
This paper proposes an effective spatiotemporal saliency model for unconstrained videos with complicated motion and complex scenes. First, superpixel-level motion and color histograms as well as global motion histogram are extracted as the features for saliency measurement. Then a superpixel-level graph with the addition of a virtual background node representing the global motion is constructed, a...
