Abstract

A method for action localization is disclosed. The method includes dividing a video comprising a first number of frames into a second number of clips, each of the clips comprising at least one of the frames; processing the clips to obtain a first clip descriptor for the each of the clips and feature maps for each of the frames; obtaining a representation of the video based on the first clip descriptor for the each of the clips; predicting an action classification of the video based on the representation of the video; calculating an importance weight for each of the feature maps based on a gradient of the action classification; and obtaining a localization map for the each of the frames based on importance weights of corresponding feature maps.
