INTERVENANT CLASSIFICATION IN AN AUDIOVISUAL DOCUMENT

摘要

This document deals with the definition of a new descriptor for audiovisual document indexing; the intervenant. We actually focus on its audiovisual localization, this is to say its place in an audiovisual sequence and its classification in 3 categories; IN, OUT or OFF. Based on the comparison of different analysis tools of both audio and video modes, we define a set of descriptors which can automatically be filled, potentially relevant to classify the intervenant localization. This decision is taken on the base of transition modeling between classes.
