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; building a database of the plurality of salient fragments; receiving a keyword; identifying a time anchor when the keyword appears in an audio track associated with the video; retrieving one or more salient fragments of the video from the database of the plurality of salient fragments based on the time anchor; generating a focalized visualization based on the one or more salient fragments of the video; tagging a human subject in the focalized visualization with a unique identifier; analyzing the focalized visualization based on the time anchor and the unique identifier to generate a behavior score; and providing the behavior score via the user device.
