| Abstract(in English) | In this paper, we describe a new integration method of speech and facial image information for person recognition. We show that the integration of speech and facial image with Dempster-Shafer's theory is very effective to improve the total performance of media-integrated recognizer especially to improve the rejection performance. Conventional media-integrated recognizers adopt the simple sum of the normalized log-likelihood values of uni-modal Bayesian recognizers and use it alone for the decision. We modified the method based on Dempster-Shafer's theory to solve the problem of Bayesian probability that can't use uncertainty. Dempster-Shafer's theory gives the attractive ideas for the integration of numerical evidences, but there was no concrete and reasonable idea for enumerating the each evidence. We solved this problem by considering the cumulative density functions of normalized log-likelihood values of correct and incorrect categories. The experimental results shows that proposed method improves the recognition performance by 18.0% compared to conventional method. |
