  • Rojas, Fernando; Solé-Casals, Jordi; Monte-Moreno, Enric; Puntonet, Carlos G.; Prieto, Alberto (Springer, 2006)
    It is well known the relationship between source separation and blind deconvolution: If a filtered version of an unknown i.i.d. signal is observed, temporal independence between samples can be used to retrieve the original ...
  • Al-Baddai, Saad; Al-Subari, Karema; Tomé, Ana Maria; Solé-Casals, Jordi; Lang, Elmar W. (Elsevier, 2016)
    Bidimensional Empirical Mode Decomposition (BEMD) interprets an image as a superposition of Bidimensional Intrinsic Mode Functions (BIMFs). They are extracted by a process called sifting, which encompasses two-dimensional ...
  • Solé-Casals, Jordi; Zaiats, Vladimir (Springer, 2010)
    This paper deals with non-linear transformations for improving the performance of an entropy-based voice activity detector (VAD). The idea to use a non-linear transformation has already been applied in the field of ...
  • Solé-Casals, Jordi; Vancea, Mihaela; March Amengual, Jaume Miquel (2014)
    This article explores the potential of ICT-based biometrics for monitoring the health status of the elderly people. It departs from specific ageing and biometric traits to then focus on behavioural biometric traits like ...
  • Comas, C.; Monte-Moreno, Enric; Solé-Casals, Jordi (Springer, 2005)
    In this paper we propose an endpoint detection system based on the use of several features extracted from each speech frame, followed by a robust classifier (i.e Adaboost and Bagging of decision trees, and a multilayer ...
  • Solé-Casals, Jordi; Caiafa, Cesar F. (Springer, 2011)
    When dealing with nonlinear blind deconvolution, complex mathematical estimations must be done giving as a result very slow algorithms. This is the case, for example, in speech processing or in microarray data analysis. ...
  • Bartés i Serrallonga, Manel; Serra Grabulosa, Josep M.; Adan, Ana; Falcón, Carles; Bargalló, Núria; Solé-Casals, Jordi (SciTePress - Science and Technology Publications, 2012)
    One problem of fMRI images is that they include some noise coming from many other sources like the heart beat, breathing and head motion artifacts. All these sources degrade the data and can cause wrong results in the ...
  • Jiménez Reifs, David; Solé-Casals, Jordi; Jutten, Christian (2000)
    El objetivo de estos programas es crear una herramienta que nos permita, de una manera fácil, entender mejor la separación de fuentes y la deconvolución de canal . Por eso se presenta el diseño, mediante Java, de una ...
  • Solé-Casals, Jordi; Vialatte, François B.; Dauwels, Justin (Springer, 2015)
    Neural signal processing is a discipline within neuroengineering. This interdisciplinary approach combines principles from machine learning, signal processing theory, and computational neuroscience applied to problems in ...
  • Lopez-de-Ipiña, Karmele; Alonso, Jesús B.; Solé-Casals, Jordi; Barroso, Nora; Faundez-Zanuy, Marcos; Ecay-Torres, Miriam; Travieso, Carlos M.; Ezeiza, Aitzol; Estanga, A. (2013)
    Alzheimer’s disease (AD) is the most prevalent form of progressive degenerative dementia and it has a high socio-economic impact in Western countries, therefore is one of the most active research areas today. Its diagnosis ...

  • Solé-Casals, Jordi; Faundez-Zanuy, Marcos (Elsevier, 2006)
    In this paper we propose the inversion of nonlinear distortions in order to improve the recognition rates of a speaker recognizer system. We study the effect of saturations on the test signals, trying to take into account ...
  • Zaiats, Vladimir; Solé-Casals, Jordi; Martí i Puig, Pere; Reig Bolaño, Ramon (Springer, 2010)
    This paper analyzes applications of cumulant analysis in speech processing. The main focus is made on an integral representation for cUl1luJants using integrals involving cyclic products of kernels. These integrals serve ...
  • Travieso, Carlos M.; Alonso, Jesús B.; Orozco-Arroyave, J.R.; Solé-Casals, Jordi; Gallego Jutglà, Esteve (Springer, 2013)
    This work describes a novel system for characterizing Laryngeal Pathologies using nonlinear dynamics, considering different complexity measures that are mainly based on the analysis of the time delay embedded space. The ...
  • Solé-Casals, Jordi; Travieso, Carlos M.; Ferrer, Miguel A.; Alonso, Jesús B.; Briceno, Juan Carlos (Springer, 2009)
    In this work we present a simulation of a recognition process with perimeter characterization of a simple plant leaves as a unique discriminating parameter. Data coding allowing for independence of leaves size and orientation ...

    Introducción. Uno de los paradigmas más utilizados en el estudio de la atención es el Continuous Performance Test (CPT). La versión de pares idénticos (CPT-IP) se ha utilizado ampliamente para evaluar los déficits de ...
  • Solé-Casals, Jordi; Monte-Moreno, Enric (Springer, 2005)
    In this paper we present a method for blind deconvolution of linear channels based on source separation techniques, for real word signals. This technique applied to blind deconvolution problems is based in exploiting ...
  • Babaie-Zadeh, Massoud; Solé-Casals, Jordi; Jutten, Christian (2003)
    In this paper, a new algorithm for blind inversion of Wiener systems is presented. The algorithm is based on minimization of mutual information of the output samples. This minimization is done through a Minimization-Projection ...
  • Taleb, Anisse; Solé-Casals, Jordi; Jutten, Christian (Springer, 1999)
    A system in which a linear dynamic part is followed by a non linear memoryless distortion a Wiener system is blindly inverted This kind of systems can be modelised as a postnonlinear mixture and using some results ...
  • Bermejo, Sergio; Solé-Casals, Jordi (IEEE, 2004)
    Electronic noses and tongues are two recent examples in chemical sensing that employ statistical array techniques in order to overcome the intrinsic limitations of current solid-state chemical sensors like ion-selective ...
