20 p, 2.1 MB Improvement of Modal Matching Image Objects in Dynamic Pedobarography using Optimization Techniques / Tavares, João Manuel R. S. (Universidade do Porto. Departamento de Engenharia Mecânica e Gestão Industrial) ; Ferreira Bastos, Luísa (Instituto de Engenharia Mecânica e Gestão Industria (Porto, Portugal). Laboratório de Óptica e Mecânica Experimental)
This paper presents an approach for matching objects in dynamic pedobarography image sequences, based on finite element modeling and modal analysis. The determination of correspondences between nodal objects is improved using optimization techniques and, because the number of elements of each object is not necessary the same, a new algorithm to match excess nodes is proposed.

12 p, 577.9 KB Area and Volume Restoration in Elastically Deformable Solids / Kelager, Micky (University of Copenhagen. Department of Computer Science) ; Fleron, Anders (University of Copenhagen. Department of Computer Science) ; Erleben, Kenny (University of Copenhagen. Department of Computer Science)
This paper describes an improvement of a classical energy-based model to simulate elastically deformable solids. The classical model lacks the ability to prevent the collapsing of solids under influence of external forces, such as user interactions and collision. [...]

11 p, 356.4 KB Simultaneous and Causal Appearance Learning and Tracking / Melenchón, J. (Universitat Ramon Llull) ; Iriondo, I. (Universitat Ramon Llull) ; Meler, L. (Universitat Ramon Llull)
A novel way to learn and track simultaneously the appearance of a previously non-seen face without intrusive techniques can be found in this article. The presented approach has a causal behaviour: no future frames are needed to process the current ones. [...]

(Informatics & Telematics Institute (Grècia))
This paper presents a new approach for human walking modeling from monocular image sequences. A kinematics model and a walking motion model are introduced in order to exploit prior knowledge. The proposed technique consists of two steps. [...]

16 p, 1.5 MB Combining Particle Filter and Population-based Metaheuristics for Visual Articulated Motion Tracking / Pantrigo, Juan José (Universidad Rey Juan Carlos. Departamento de Informática, Estadística y Telemática) ; Sánchez, Ángel (Universidad Rey Juan Carlos. Departamento de Informática, Estadística y Telemática) ; Gianikellis, Kostas (Universidad de Extremadura. Departamento de Actividad Musical, Plastica y Corporal) ; Montemayor, Antonio S. (Universidad Rey Juan Carlos. Departamento de Informática, Estadística y Telemática)
Visual tracking of articulated motion is a complex task with high computational costs. Because of the fact that articulated objects are usually represented as a set of linked limbs, tracking is performed with the support of a model. [...]

12 p, 527.1 KB Ear Biometrics Based on Geometrical Feature Extraction / Choraś, Micha (University of Technology and Agriculture (Polònia). Institute of Telecommunication)
Biometrics identification methods proved to be very efficient, more natural and easy for users than traditional methods of human identification. In fact, only biometrics methods truly identify humans, not keys and cards they posses or passwords they should remember. [...]

Departamento de Matemáticas e Informática) ; Perales, Francisco J. (Universitat de les Illes Balears. Departamento de Matemáticas e Informática)
The proposed work is part of a project that aims for the control of a videogame based on hand gesture recognition. This goal implies the restriction of real-time response and unconstrained environments. [...]

12 p, 683.5 KB A Comparison Framework for Walking Performances using aSpaces / Villanueva Pipaón, Juan José (Universitat Autònoma de Barcelona. Departament de Ciències de la Computació) ; Gonzàlez i Sabaté, Jordi (Universitat Autònoma de Barcelona. Departament de Ciències de la Computació) ; Varona, Javier (Universitat de les Illes Balears. Departament de Matematiques i Informàtica & Unitat de Gràfics i Visió) ; Roca i Marvà, Francesc Xavier (Universitat Autònoma de Barcelona. Departament de Ciències de la Computació) ; Gonzàlez, Jordi
In this paper, we address the analysis of human actions by comparing different performances of the same action executed by different actors. Specifically, we present a comparison procedure applied to the walking action, but the scheme can be applied to other different actions, such as bending, running, etc. [...]

In this paper, a new method for image deformation is presented. It is based upon decomposition of the deformation problem into basic physical laws. Unlike other methods that solve a differential or an energetic formulation of the physical laws involved, we encode the basic laws using computational algebraic topology. [...]

(Ecole Polytechnique Fédérale de Lausanne. Swarm-Intelligent System Group)
In video surveillance and sports analysis applications, object trajectories offer the possibility of extracting rich information on the underlying behavior of the moving targets. To this end we introduce an extension of Point Distribution Models (PDM) to analyze the object motion in their spatial, temporal and spatiotemporal dimensions. [...]
