    • openAccess   A Parallel Approach to HRTF Approximation and Interpolation Based on a Parametric Filter Model 

      Ramos, German; Cobos, Maximo; Bank, Balázs; BELLOCH, JOSE A. Institute of Electrical and Electronics Engineers (IEEE) (2017-10)
      Spatial audio-rendering techniques using head-related transfer functions (HRTFs) are currently used in many different contexts such as immersive teleconferencing systems, gaming, or 3-D audio reproduction. Since all these ...

    • closedAccess   A penalized likelihood method for nonseparable space–time generalized additive models 

      Mosammam, Ali M.; Mateu, Jorge Springer Verlag (2018-07)
      In this paper, we study space-time generalized additive models. We apply the penalyzed likelihood method to fit generalized additive models (GAMs) for nonseparable spatio-temporal correlated data in order to improve the ...

    • openAccess   Environment-Aware Regression for Indoor Localization based on WiFi Fingerprinting 

      Mendoza-Silva, Germán Martín; Costa, Ana Cristina; Torres-Sospedra, Joaquín; Painho, Marco; Huerta, Joaquin Institute of Electrical and Electronics Engineers (2021-04-19)
      Data enrichment through interpolation or regression is a common approach to deal with sample collection for Indoor Localization with WiFi fingerprinting. This paper provides guidelines on where to collect WiFi samples, and ...

    • openAccess   Influence of Measured Radio Map Interpolation on Indoor Positioning Algorithms 

      Bravenec, Tomáš; Gould, Michael; Fryza, Tomas; Torres-Sospedra, Joaquín IEEE (2023-07-24)
      Indoor positioning and navigation increasingly have become popular, and there are many different approaches, using different technologies. In nearly all of the approaches, the locational accuracy depends on signal propagation ...

    • openAccess   La interpolación aplicada al procesamiento de imágenes digitales 

      Roncero García, Alba Universitat Jaume I (2019-10)
      Durante este proyecto se tratan conocimientos generales del procesamiento de imágenes, y más concretamente cómo se aplica la interpolación en este proceso.También se explican en detalle los métodos de interpolación mas ...

    • openAccess   RF-Based Location Using Interpolation Functions to Reduce Fingerprint Mapping 

      Ezpeleta, Santiago; Claver, José M.; Pérez Solano, Juan J.; Martí Avilés, José Vicente MDPI (2015-10)
      Indoor RF-based localization using fingerprint mapping requires an initial training step, which represents a time consuming process. This location methodology needs a database conformed with RSSI (Radio Signal Strength ...

    • openAccess   Situation Goodness Method for Weighted Centroid-Based Wi-Fi APs Localization 

      Mendoza-Silva, Germán Martín; Torres-Sospedra, Joaquín; Huerta, Joaquin; Montoliu Colás, Raul; Benítez, Fernando; Belmonte-Fernández, Óscar Springer (2016-10-13)
      Knowing the location of Wi-Fi antennas may be critical for indoor localization. However, in a real environment, their positions may be unknown since they can be managed by external entities. This paper introduces a new ...
