Abstract: The present disclosure relates to systems and methods for classifying videos based on video content. For a given video file including a plurality of frames, a subset of frames is extracted for processing. Frames that are too dark, blurry, or otherwise poor classification candidates are discarded from the subset. Generally, material classification scores that describe type of material content likely included in each frame are calculated for the remaining frames in the subset. The material classification scores are used to generate material arrangement vectors that represent the spatial arrangement of material content in each frame. The material arrangement vectors are subsequently classified to generate a scene classification score vector for each frame. The scene classification results are averaged (or otherwise processed) across all frames in the subset to associate the video file with one or more predefined scene categories related to overall types of scene content of the video file.

Abstract: A system and methods are provided for analyzing user interactions with a media content discovery system using statistical hypothesis testing techniques. As used herein, a media content discovery system generally represents any service that enables users to browse, view, record, purchase, and/or otherwise interact with media content. Examples of media content that may be made available to users via a media content discovery system include, without limitation, movies, television shows, music, etc. Users may interact with a media content discovery system using any of a number of different types of computing devices, including set-top boxes, desktop computers, laptops, handheld devices, game consoles, etc., and over one or more networks, such as the Internet.
