VIDEO CLASSIFICATION AND PREVIEW SELECTION

Abstract:

Systems and methods select and provide video snippets in a matrix interface. Example methods include obtaining a portion of a video stream, assigning the portion to a class, determining that the assigned class is a promoted class, and generating a snippet for the video stream using the portion. Other example methods include determining, using a trained video classifier, a set of video streams that have at least one portion that is classified as a promoted class, calculating, for each of the video streams in the set, an aggregate score for the video stream, selecting video streams with highest aggregate scores, generating a snippet for each of the selected video streams, and providing the snippets in a user interface. Methods may also include selecting portions of video streams that are responsive to a user-provided parameter and generating a snippet for the video stream a portion classified as a promoted class.
