To alleviate the computational expensive segmentation step of existing proposals, we propose bypassing the segmentations completely by generating proposals directly from the dense trajectories used to represent videos during classification. Our Action localization Proposals from dense Trajectories (APT) use an efficient proposal generation algorithm to handle the high number of trajectories in a video. Our spatio-temporal proposals are faster than current methods and outperform the localization and classification accuracy of current proposals on the UCF Sports, UCF 101, and MSR-II video datasets.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The BMVC2015 paper entitled APT: Action localization proposals from dense trajectories by Jan van Gemert, Mihir Jain, Ella Gati and Cees Snoek is now available.\u00a0This paper is on action localization in video with the aid of spatio-temporal proposals.
