A multimodal approach to extract optimized audio features for speaker detection

Jean-Philippe Thiran, Murat Kunt, Torsten Butz, Patricia Besson

We present a method that exploits an information theoretic framework to extract optimal audio features with respect to the video features. A simple measure of mutual information between the resulting audio features and the video ones allows to detect the a ...

Method for marking a compressed digital video signal

Touradj Ebrahimi, Frédéric Jordan

A method for marking a compressed digital video signal by embedding a digital signature in the compressed video signal, the signal representing a series of at least two video images, each image being divided into a plurality of regions, the signal includin ...

Feature point extraction using scale-space representation

Touradj Ebrahimi, Yousri Abdeljaoued

An algorithm for feature point extraction is presented. It is based on a scale-space representation of the image as well as a system for tracking across scales. Using synthetic and real images, it is shown that the proposed algorithm produces stable and we ...

Multi-Modal Audio-Visual Event Recognition for Football Analysis

Jean-Marc Odobez, Samy Bengio, Mark Barnard

The recognition of events within multi-modal data is a challenging problem. In this paper we focus on the recognition of events by using both audio and video data. We investigate the use of data fusion techniques in order to recognise these sequences withi ...
