I am pleased to announce that the following paper has been accepted to the Icassp 2007 (http://www.icassp2007.org/) an International Conference on Acoustics, Speech, and Signal Processing Geoffroy Fouquier, Laurence Likforman, Jérôme Darbon and Bülent Sankur. The Biosecure Geometry-based System for Hand Modality. We present an identification and authentification system based on hand modality which is part of a reference system for all modalities developed within the Biosecure consortium. It relies on simple geometric features extracted from hand boundary. The different steps of this system are detailed, namely: pre-processing, feature extraction and hand matching. This system has been tested on the Biosecure hand database which consists of 4500 hand images of 750 individuals. Results are detailed with respect to different enrolment conditions such as population size, enrolment size, and image resolution. -- Geoffroy Fouquier Geoffroy.Fouquier@lrde.epita.fr
