analysis for audio-visual speech recognition<br>

Signal Processing Lab (LTS5), Lausanne, Switzerland.<br>
<br>
Place: ECE Conference Room, 4164 HFH<br>
Time: 11AM, Monday, March 16<br>
<br>
After a short introduction presenting our group and our main research<br>
topics, I will address the problem of audio-visual speech recognition,<br>
i.e. a typical example of multimodal signal analysis, when we want to<br>
extract and exploit information coming from two different but<br>
complementary signals: an audio and a video channel. We will discuss<br>
two important aspects of this analysis. We will first present a new<br>
feature extraction algorithm based in information theoretical<br>
principles, and show its performances, compared to other classical<br>
approaches, in our multimodal context. Then we will discuss multimodal<br>
information fusion, i.e. how to combine information from those two<br>
channels for optimal classification.<br>
<br>
Short bio:<br>
Jean-Philippe Thiran was born in Namur, Belgium, in 1970. He received<br>
the Elect. Eng. and Ph.D. degrees from the Universite catholique de<br>
Louvain (UCL), Louvain-la-Neuve, Belgium, in 1993 and 1997,<br>
respectively. He joined the Signal Processing Laboratory (LTS) of the<br>
Swiss Federal Institute of Technology (EPFL), Lausanne, Switzerland,<br>
in February 1998 as a Senior Lecturer. Since January 2004, he has been<br>
an Assistant Professor, responsible for the Image Analysis Group. His<br>
current scientific interests include image segmentation, prior<br>
knowledge integration in image analysis, partial differential<br>
equations and variational methods in image analysis, multimodal signal<br>
processing, medical image analysis, including multimodal image<br>
registration, segmentation, computer-assisted surgery, and diffusion<br>
MRI. He is author or co-author of two 4 book chapters, 69 journal<br>
papers, and some 130 peer-reviewed papers published in proceedings of<br>
international conferences. He holds four international patents. Dr.<br>
Thiran was Co-Editor-in-Chief of Signal Processing (published by<br>
Elsevier Science) from 2001 to 2005. He is currently an Associate<br>
Editor of the International Journal of Image and Video Processing<br>
(published by Hindawi), and member of the Editorial Board of Signal,<br>
Image and Video Processing (published by Springer). He was the General<br>
Chairman of the 2008 European Signal Processing Conference (EUSIPCO<br>
2008). He is a senior member of the IEEE, and member of the MLSP and<br>
IVMSP technical committees of the IEEE Signal Processing Society.<br>
