  • A recursive approach to Multiscalar Data Interpolation of sparsely sampled sea surface measurements at different spatial resolutions
    Reig Bolaño, Ramon; García Ladona, Emili; Parisi Baradad, Vicenç; Martí i Puig, Pere (IEEE, 2008)
    Abstract- In many oceanographic studies there is a need to reconstruct a signal from a set of sparse measurements. We propose an algorithm to iteratively approximate the intermediate values between irregularly sampled ...
  • Applications of Cumulants in Speech Processing
    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 ...
  • Coding of Biosignals Using the Discrete Wavelet Decomposition
    Reig Bolaño, Ramon; Martí i Puig, Pere; Solé-Casals, Jordi; Zaiats, Vladimir; Parisi Baradad, Vicenç (Springer, 2010)
    Abstract. Wavelet derived codification techniques are widespread used in image codifiers. The wavelet based compression methods are adequate for representing transients. In this paper we explore the use of the discrete ...
  • Games4Learning: Cómo integrar juegos serios en itinerarios de aprendizaje personalizados?
    Grau Carrión, Sergi; Reig Bolaño, Ramon; Puig, Anna; López, Maite; Rodríguez, Immaculada (Institute of Electrical and Electronics Engineers Inc., 2015)
    Una enseñanza de calidad y el buen aprendizaje de las disciplinas STEM (Science, Technology, Engineering, and Mathematics) son factores esenciales en la motivación y la formación de profesionales en la sociedad actual. ...
  • Image Processing to Detect and Classify Situations and States of Elderly People
    Reig Bolaño, Ramon; Martí i Puig, Pere; Bajo, Javier; Rodríguez, Sara; De Paz, Juan F.; Rubio, Manuel P. (Springer, 2011)
    Abstract. Monitoring and tracking of elderly people using vision algorithms is an strategy gaining relevance to detect anomalous and potentially dangerous situations and react immediately. In general vision algorithms ...
  • Market Stock Decisions Based on Morphological Filtering
    Martí i Puig, Pere; Reig Bolaño, Ramon; Bajo, Javier; Rodríguez, Sara (Springer, 2010)
    In this paper we use a nonlinear processing technique based on mathematical morphology to develop a simple day trading system that automatically decides the timing to commute the marked strategy in terms of sort/long ...
  • Mathematical Morphology Preprocessing to Mitigate AWGN Effects: Improving Pitch Tracking Performance in Hard Noise Conditions
    Martí i Puig, Pere; Solé-Casals, Jordi; Reig Bolaño, Ramon; Zaiats, Vladimir (Springer, 2010)
    Abstract. In this paper we show how a nonlinear preprocessing of speech signal -with high noise- based on morphological filters improves the performance of robust algorithms for pitch tracking (RAPT). This result happens ...
  • Score Function for Voice Activity Detection
    Solé-Casals, Jordi; Martí i Puig, Pere; Reig Bolaño, Ramon; Zaiats, Vladimir (Springer, 2010)
    In this paper we explore the use of non-linear transformations in order to improve the performance of an entropy based voice activity detector (VAD). The idea of using a non-linear transformation comes from some ...
