The methods improve upon the prior art which either require trimmed video segments including only a single activity depicted therein, or untrimmed video segments including relatively few actions, persons, or objects of interest, thereby directing the classification. Instead, the methods utilize a plurality of tubelets used to represent discreet actions, persons, and objects of interest within the comprehensive untrimmed video segment. The tubelets are localized to correct for pixel-level foreground-background biases, which are then turned into short spatio-temporal action tubelets that are passed to a classification network to obtain multi-label predictions. After classification, the tubelets are be linked together to obtain the final detections with varying lengths, and the method merges the short action tubelets into final action detections."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods of real-time spatio-temporal activity detection and categorization from untrimmed video segments","description":"Methods of detecting and categorizing an action in an untrimmed video segment regardless of the scale of the action and the close proximity of other actions.
