Document Type and Number:
WIPO Patent Application WO/2020/196985
Kind Code:
A1
Abstract:
The present invention may provide an apparatus and method for video action recognition and action section detection, which can perform temporal action localization on a video by being trained using a training video in which only a simple action label is annotated, thereby reducing temporal and cost burdens for obtaining the training video, and can recognize an accurate temporal location of an action with temporal consistency by extracting, from the video, feature maps according to segments to analyze action reliability according to the segments and a semantic similarity between the segments regarding a same action, and applying a weight to the action reliability according to the segments on the basis of the semantic similarity between the segments.
