ENHANCED COMMERCIAL DETECTION THROUGH FUSION OF VIDEO AND AUDIO SIGNATURES

摘要

A system and method for detecting commercials from other programs in a stored content. The system comprises an image detection module that detects and extracts faces in a specific time window. The extracted faces are matched against the detected faces in the subsequent time window. If none of the faces match, a flag is set, indicating a beginning of a commercial portion. A sound or speech analysis module verifies the beginning of the commercial portion by analyzing the sound signatures in the same time windows used for detecting faces.
