In this paper we describe the acquisition and content of a large multi-modal database intended for training and testing of multi-modal veriication systems. The XM2VTSDB database ooers synchron-ised video and speech data as well as image sequences allowing multiple views of the face. It consists of digital video recordings taken of 295 hundred subjects at(More)
This paper considers the segmentation of range image measurements into surface patches which are either plane or curved and which are described formally by a function. After a formal description of the segmentation, we present and compare three methods suited for plane and curved patch segmentation and show the results of experiments conducted for testing(More)
This paper presents the European ACTS project (( MZVTS )) which stands for Multi Modal Verification f o r Teleservices and Security Applications. The primary goal of this project is to address the issue of secured access to local and centralised services in a multimedia environment. The main objective is to extend the scope of application of networkbased(More)
In Switzerland, the daily and annual profiles of electrical energy supply are deeply reshaped by the increasing importance of non-flexible renewable sources, i.e. solar and wind, slowly replacing nuclear power plants. Load shifting can be a special help, adapting consumption to this new production, allowing to develop and implement new storage solutions. In(More)
This paper describes experiments of a text-independent speaker verification method that has been evaluated on two laboratory databases (M2VTS and XM2VTS) and on one field test database (LoCoMic). This work has been performed within the European ACTS-M2VTS project (Multi-Modal Verification for Teleservices and Security Applications) which is concerned with(More)
We propose multi-modal person veriication using voice and images as a solution to the secured access problem. The necessary i/o devices are now standard, cheaply available and, most importantly, constitute the two most important human communication modalities. The visual part currently involves i) matching of a coarse grid containing Gabor phase information(More)
