Automatic Hand Detection in Color Images based on skin region verification

Sofiane Medjram, Chaouki Babahenini, Yamina Mohamed Ben Ali, Abdelmalik Taleb-Ahmed

Among the modern means of communications that appeared recently, there is the natural computer interaction using hands. Several methods have been proposed for their detection in the literature, and the common methods are based on skin color. The majority of these methods perform on images…

Thierry-Marie Guerra, Raymundo Márquez Borbόn, Alexandre Kruszewski, Miguel Bernal

This paper is concerned with state estimation for continuous-time nonlinear systems. By means of a polytopic exact representation of the system using interpolation functions whose premise variables can be unmeasured, the differential mean value theorem and a quadratic Lyapunov function are used to…

Arm-trunk coordination in wheelchair initiation displacement

Soufien Chikh, Cyril Garnier, Arnaud Faupin, Antonio Pinti, Samuel Boudet, Fairouz Azaiez, Eric Watelain

Arm-trunk coordination during the initiation of displacement in manual wheelchair is a complex task. The objective of this work is to study the arm-trunk coordination by measuring anticipatory and compensatory postural adjustments. Nine healthy subjects participated in the study after being trained…

Contribution of neurosensory Posturotherapy in the management of specific chronic pain syndrome

Frédéric Viseux, Antoine Lemaire, Pascal Charpentier

Objectives Chronic pain syndromes are frequently associated with balance disorders [1]. For example, studies showed a linear relationship between pain and stability [1] in no-specific low back pain [2]. The reexamination of the links between nerves and pain [3] modifies the traditional perception…

Modulation of intermuscular coherence between homologous muscles reflects different common neural drive regulating bilateral contractions

Emilie Mathieu, Gauthier Desmyttere, Emilie Simoneau-Buessinger, Sylvain Cremoux

Objectives In healthy adults, homologous muscle activations appear during bilateral contractions (BI) and can be induced during unilateral contractions (UNI) at high force level. After brain injury, involuntary homologous muscle activations during UNI can have neurological significance. Although…

Modélisation et caractérisation de la stabilité en position assise chez les personnes vivant avec une lésion de la moelle épinière, Modelling sitting stability for people living with a spinal cord injury

Mathias Blandeau

Les personnes vivant avec une lésion de la moelle épinière (LMÉ) subissent une réduction drastique de leurs capacités sensori-motrices en dessous du niveau de la lésion. Cette pathologie influence négativement leur contrôle postural, vu comme le résultat de contributions actives, passives et…, The ability to maintain stability in an unsupported sitting position often becomes challenging after an individuals is affected by a spinal cord injury (SCI). In order to better understand sitting postural control as a combination of active, passive and neuronal contribution, a modelling approach…

A Novel Heterogeneous Approximate Multiplier for Low Power and High Performance

Ihsen Alouani, Hamzeh Ahangari, Özcan Özturk, Smail Niar

Approximate computing is a design paradigm considered for a range of applications that can tolerate some loss of accuracy. In fact, the bottleneck in conventional digital design techniques can be eliminated to achieve higher performance and energy efficiency by compromising accuracy. In this letter…

Takagi-Sugeno fuzzy descriptor approach for trajectory control of a 2-DOF serial manipulator

van Anh Nguyen Thi, Laurent Vermeiren, Antoine Dequidt, Tran Anh-Tu Nguyen, Michel Dambrine, Le Cung

This paper presents a Takagi-Sugeno fuzzy descriptor approach for nonlinear control of a 2-DoF serial manipulator. The design goal is to achieve high tracking performance in case of circular trajectory while significantly reducing the numerical complexity of the designed controller through an…

From Persona to Living Persona, Preliminary Data from a Pilot Study in HCI Education

Christophe Kolski, Bruno Warin

The Persona technique consists in introducing, in the process of realization of a product (good or service), one or more fictitious personages representing users of the product to be designed. In this paper, we present a preliminary study on the adaptation of the Persona technique to promote the…
