This paper presents an automatic FDP (Facial Definition Parameters) and FAP (Facial Animation Parameters) generation method from an image sequence that captures a frontal face. The proposed method is based on facial feature tracking without markers on a face. We present an efficient method to extract 2D facial features and to generate the FDP by applying 2D features to a generic face model. We ...

A secret sharing scheme permits a secret to be shared among participants in such a way that only qualiied subsets of participants can recover the secret. If any non qualiied subset has absolutely no information about the secret, then the scheme is called perfect. Unfortunately, in this case the size of the shares cannot be less than the size of the secret. Krawczyk 9] showed how to improve this...

We describe a knowledge based system for microbiological laboratory data validation and bacteria infections monitoring. The knowledge base has been obtained from international standard guidelines for microbiological laboratory practice, from experts’ suggestions and from data mining. In this work, we evaluate the system in terms of accuracy on a test dataset.

A comparison has been made of the radioisotope dilution-coated charcoal method and a microbiological assay (with L. leichmannii as test organism) for determining the concentration of vitamin B(12) in serum. A satisfactory correlation was found between the results of the two methods. Under appropriate conditions the reproducibility of the radioisotope method compared favourably with that of the ...

LUCIA, a new Italian talking head based on a modified version of the Cohen-Massaro’s labial coarticulation model is described. A semi-automatic minimization technique, working on real cinematic data, acquired by the ELITE optoelectronic system, was used to train the dynamic characteristics of the model. LUCIA is an MPEG-4 standard facial animation system working on standard FAP visual parameter...

We present the first fair e-cash system with a compact wallet that enables users to spend efficiently k coins while only sending to the merchant O(λ log k) bits, where λ is a security parameter. The best previously known schemes require to transmit data of size at least linear in the number of spent coins. This result is achieved thanks to a new way to use the Batch RSA technique and a tree-bas...

We consider the problem of estimating the length of a shortest path in a DAG whose edge lengths are known only approximately but can be determined exactly at a cost. Initially, each edge e is known only to lie within an interval [le; he]; the estimation algorithm can pay ce to nd the exact length of e. In particular, we study the problem of nding the cheapest set of edges such that, if exactly ...

At Crypto 2013, Coron, Lepoint, and Tibouchi (CLT) proposed a practical Graded Encoding Scheme (GES) over the integers, which has very similar cryptographic features to ideal multilinear maps. In fact, the scheme of Coron et al. is the second proposal of a secure GES, and has advantages over the first scheme of Garg, Gentry, and Halevi (GGH). For example, unlike the GGH construction, the subgro...

We construct the first constant-size hierarchical identity-based signature (HIBS) without random oracles the signature size is O(λs) bits, where λs is the security parameter, and it is independent of the number of levels in the hierarchy. We observe that an efficient hierarchical identity-based signcryption (HIBSC) scheme without random oracles can be compositioned from our HIBS and Boneh, Boye...
