Region search is widely used for object localization in computer vision area. After projecting the score of an image classifier into an image plane, region search aims to find regions that precisely localize desired objects. The popular region search methods, such as efficient subwindow search and efficient region search, usually find regions with maximal(More)
Many abstract bipolar concepts are usually represented by metaphors on vertical dimensions (e.g. positive-up, negative-down). However, several studies have found an asymmetry in the way in which individuals process bipolar dimensions, with +polarities being stronger than -polarities. The current research focused on moral metaphors on a vertical dimension(More)
Trajectory-based features have become popular for action recognition and achieve the state-of-the-art results on a variety of datasets. In this paper, we propose a novel framework to improve the performance of action recognition. Specifically, we first apply the nonuniform sampling method to efficiently select features for given actions. The proposed hybrid(More)
