The paper presents results of the face verification contest that was organized in conjunction with International Conference on Pattern Recognition 2000 . Participants had to use identical data sets from a large, publicly available multimodal database XM2VTSDB. Training and evaluation was carried out according to an a priori known protocol ().… (More)
Biometric person identity authentication is gaining more and more attention. The authentication task performed by an expert is a binary classification problem: reject or accept identity claim. Combining experts, each based on a different modality (speech, face, fingerprint, etc.), increases the performance and robustness of identity authentication systems.… (More)
Personal computing and communication devices such as computers, PDAs, and Author: Please 1. spell out PAD here mobile phones are moving to their next generation in which the end user will be able to access a multitude of information with a single device either locally or through a network. One likely trend in future personal computing and personal… (More)
MPEG-7 camera extends the capabilities of conventional cameras by analyzing its scene in order to generate a content-based description according to the recently approved MPEG-7 standard. This gives to the camera a large variety of current and potential applications, such as surveillance, augmented reality, and virtual display. This paper provides an… (More)
The paper presents the European ACTS project " M2VTS " which stands for Multi Modal Verification for 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 network based… (More)
A n algorithm for feature point extraction i s presented. I t is based on a scale-space representation of the image as well as a system for tracking across scales. Using synthetic and real images, i t is shown that the proposed algorithm produces stable and well-localized feature points estimates-two essential propaties for video applications.
Acknowledgements This thesis is the result of four years of work. There has been ups and downs but fortunately many people have been by my side when I needed their help and support. First of all, I would like to thank Professor Touradj Ebrahimi, my supervisor. I appreciate the freedom he gave me in my research and the advices I received from him every time… (More)
