Biometrics: Past, Present and Future

Biometrics is the science of establishing human identity based on the physical and behavioral attributes of an individual such as fingerprints, face, iris, voice and signature. In its simplest form, biometric recognition involves comparing two signals, such as fingerprint images, to determine the probability that they originated from the same source (i.e., individual). The pronounced need for large-scale automated human recognition systems has resulted in the incorporation of biometric solutions in border security systems (e.g., US-VISIT program), access control applications (e.g., laptops), criminal investigations (e.g., AFIS), time-and-attendance technology (e.g., hand geometry readers) and national ID cards (e.g., Hong Kong SmartID). The ascent of biometrics over the past decade belies its humble beginnings in the late 19th century, when the technology was confined to the use of manually recorded human anthropometric measurements for identifying recidivists. Advances in the field of sensor manufacturing, signal processing, pattern recognition, computer vision and machine learning have led to the design of elegant biometric systems that can rapidly establish identity albeit with a few errors.

In the current biometric literature, issues related to biometric data security, privacy, system scalability, database indexing, sensor interoperability and recognition in non-ideal unconstrained environments have been emphasized. This talk will examine the recent progress made in biometrics and discuss some of the interesting problems being addressed by researchers in this field.

Urban Computing and Smart Cities: Opportunities and Challenges

City-wide urban infrastructures are increasingly reliant on networked technology to improve and expand their services. As a side effect of this digitalization, large amounts of data –digital footprints-- can be sensed and analyzed to uncover patterns of human urban behavior and to augment the city experience of its citizens. In my talk, I will introduce the main concepts, opportunities and challenges in this emerging area of urban computing and will present some recent work on analyzing the digital footprints from the urban infrastructure. I will show how these digital footprints can be used to infer cultural and geographic aspects of the city and predict aspects of the city’s behavior. Finally, I will also illustrate a few examples of mobile applications that enhance the experience of the city by seamlessly combining digital and physical information.

The Evolution of Satellite Communications - A Signal Processing Perspective

Following 1945 A. C. Clarke intuition of the satellite Geostationary concept, satellite communication technology has been becoming a reality in the late 60’s making possible intercontinental voice and video communications. In the 70’s also mobile satellite telecommunications for maritime users became a reality. The development of satellite telecommunication technology has been driving the introduction of advanced coding schemes such as the Viterbi’s algorithm and multiple access schemes such as Time Division Multiple Access and associated burst mode demodulator. These two technologies were the base for the terrestrial GSM digital mobile standard which had an unprecedented commercial success.

Nowadays the technology pioneering role of satellite communications appears to be shadowed by the fast pace development of wireless terrestrial technologies. In this talk a review of most promising signal processing techniques adopted or candidate for being adopted in modern satellite networks. Differences in the satellite operating system conditions compared to terrestrial networks will be stressed as well as the required adaptationsof signal processing techniques.

Content Creation for Stereoscopic 3D and Beyond

2010 was the year of breakthrough for 3D video. Stereoscopic 3D is established in cinema, on Blu-ray, TV, PCs, laptops, and mobile devices. Since technology for stereo 3D is mature and content creation is understood well enough, these developments are expected to be sustainable this time. Most current systems rely on classical approaches to 3D video, i.e. representation as stereo or multiview video, coding and transmission using simulcast, frame-compatible composition or MVC. More advanced “next generation” approaches exploit some kind of understanding of the 3D scene geometry such as depth or disparity, in order to extend functionality and increase efficiency. This includes for instance flexible adjustment of depth impression to viewing conditions and user preferences or support of autostereoscopic multiview displays. Also content creation for classical stereo 3D can greatly benefit from such 3D geometry aware processing. Naturally such advanced 3D video representation formats require advanced processing algorithms, e.g., to extract 3D geometry and to render virtual views. Such advanced 3D video representation and processing will be the focus of this talk.

Adaptive Learning in a World of Projections

The task of parameter/function estimation has been at the center of scientific attention for a long time and it comes under different names such as filtering, prediction, beamforming, curve fitting, classification, regression.

In this talk, the estimation task is treated in the context of set theoretic estimation arguments. Instead of a single optimal point, we are searching for a set of solutions that are in agreement with the available information, which is provided to us in the form of a set of training points and a set of constraints. Each point in the training data set, as well as each one of the constraints, is associated with a convex set, constructed according to a (convex) loss function (differentiable or not).

The goal of this talk is to present a general tool for parameter/function estimation, under a set of convex constraints, both for classification as well as regression tasks, in a time adaptive setting in (infinite dimensional) Reproducing Kernel Hilbert spaces (RKHS).

The algorithmic scheme consists of a sequence of projections, of linear complexity with respect to the number of unknown parameters. Our theory proves that such a scheme converges to the intersection of all (with the possible exception of a finite number of) the convex sets, where the required solution lies. The performance of the methodology is demonstrated in the context of nonlinear classification and robust beamforming in communication systems.

The work has been carried out in cooperation with Kostas Slavakis and Isao Yamada.

Acoustic Signal Processing for Natural Interactive and Immersive Human/Machine Interfaces

Since the very beginning of audio signal reproduction, immersion was always seen as a crucial feature of high quality. With the arrival of teleconferencing systems, immersive multichannel reproduction became part of telecommunication systems, and the according terminals developed into multi-functional human/machine interfaces, supporting not just telecommunication but also gaming, simulators, control consoles interactive home theatres and many other purposes. Along with increasingly powerful and cost-effective signal processing hardware, the according acoustic signal processing algorithms developed dramatically over the last decade striving for perfect solutions for the fundamental problems of acoustic interfaces: Acoustic feedback from loudspeakers to microphones, noise and interfering sources, and reverberation in enclosures.

In this talk, we will shortly review the fundamental problems and then highlight some recent developments in acoustic echo control for massive multichannel reproduction, signal extraction, source localization, dereverberation, as well as distant-talking speech recognition. Finally, we also will speculate on promising avenues for future research.

Towards Exaflop Supercomputers

Having recently surpassed the Petascale barrier, supercomputers designers and users are now facing the next challenge. A thousand fold performance increase that if the improvement rate of the last decades continues will be reached around 2018.

Being power the main constraint and facing many hardware challenges, software is probably the biggest one. Worldwide and cooperative initiatives are being started to perform research facing such objective.

The Barcelona Supercomputing Center is involved in such initiatives and carries out the MareIncognito research project aiming at developing some of the technologies that we consider will be of key relevance on the way to Exascale.

The talk will briefly discuss relevant issues, foreseen architectures and software approaches that will have to be developed in order to successfully install and operate such machines.
