Several papers have already shown the interest of using multiple classifiers in order to enhance the performance of biometric person authentication systems. In this paper, the authors would like to argue that the core task of biometric person authentication is actually a multiple classifier problem as such: indeed, in order ...Download Now
In this paper, the authors present a survey on the recent use of Local Binary Patterns (LBPs) for face recognition. LBP is becoming a popular technique for face representation. It is a non-parametric kernel which summarizes the local spacial structure of an image and it is invariant to monotonic gray-scale ...Download Now
In this paper, the problem of face authentication using salient facial features together with statistical generative models is addressed. Actually, classical generative models, and Gaussian Mixture Models in particular make strong assumptions on the way observations derived from face images are generated. Indeed, systems proposed so far consider that local ...Download Now
Biometric authentication performance is often depicted by a DET curve. The authors show that this curve is dependent on the choice of samples available, the demographic composition and the number of users specific to a database. They propose a two-step bootstrap procedure to take into account of the three mentioned ...Download Now
