Behavioral measurements in a video stream focalized on keywords

摘要

A system and method for analyzing behavior in a video is described. The method includes extracting a plurality of salient fragments of a video; associating a time anchor with an utterance of a first keyword in an audio track associated with the video; generating a focalized visualization, based on the time anchor, from one or more of the plurality of salient fragments of the video; tagging a human subject in the focalized visualization with a unique identifier; and analyzing behavior of the human subject, using the focalized visualization, to generate a behavior score associated with the unique identifier and the first keyword.
