This paper strives to localize the temporal extent of an action in a long untrimmed video. Where existing work leverages many examples with their start, their ending, and\/or the class of the action during training time, we propose few-shot common action localization. The start and end of an action in a long untrimmed video is determined based on just a hand-full of trimmed video examples containing the same action, without knowing their common class label. To address this task, we introduce a new 3D convolutional network architecture able to align representations from the support videos with the relevant query video segments. The network contains: (i) a mutual enhancement module to simultaneously complement the representation of the few trimmed support videos and the untrimmed query video; (ii) a progressive alignment module that iteratively fuses the support videos into the query branch; and (iii) a pairwise matching module to weigh the importance of different support videos. Evaluation of few-shot common action localization in untrimmed videos containing a single or multiple action instances demonstrates the effectiveness and general applicability of our proposal.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"735\" src=\"http:\/\/www.ceessnoek.info\/wp-content\/uploads\/2020\/08\/yang-common-action-1024x735.png\" alt=\"\" class=\"wp-image-3391\" srcset=\"https:\/\/www.ceessnoek.info\/wp-content\/uploads\/2020\/08\/yang-common-action-1024x735.png 1024w, https:\/\/www.ceessnoek.info\/wp-content\/uploads\/2020\/08\/yang-common-action-300x215.png 300w, https:\/\/www.ceessnoek.info\/wp-content\/uploads\/2020\/08\/yang-common-action-768x551.png 768w, https:\/\/www.ceessnoek.info\/wp-content\/uploads\/2020\/08\/yang-common-action.png 1624w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>The ECCV 2020 paper Localizing the Common Action Among a Few Videos by Pengwan Yang, Vincent Tao Hu, Pascal Mettes and Cees Snoek is now available.
