Person-based video summarization by tracking and clustering temporal face sequences

摘要

A method for finding a temporal face sequence (412) includes, with a physical computing system (100), analyzing frames within a shot within a video, applying a face detection function to the frames, and in response to detecting a face within one of the frames, tracing a person associated with the face both backwards and forwards through frames within the shot. A temporal face sequence (412) is then defined as a sequence of frames that include frames within the shot spanning when the person is shown.
