Robust movie character identification and the sensitivity analysis
Automatic face identification of characters in movies has drawn significant research interests and led to various applications. It is a challenging problem due to the huge variation in the appearance of each character. Although existing methods demonstrate promising results in clean environment, the performances are limited in complex movie scenes due to the noises generated during the face tracking and face clustering process. In this paper we present a robust character identification approach by incorporating a noise insensitive relationship representation and a graph matching algorithm. Beyond existing character identification approaches, we further perform explicit sensitivity analysis on character identification by introducing two types of simulated noises. Experiments validate the advantage of the proposed method.
