    Accurate segmentation of infant brain magnetic resonance (MR) images into white matter (WM), gray matter (GM), and cerebrospinal fluid (CSF) is an indispensable foundation for early studying of brain growth patterns and ...
  • Measuring traffic lane-changing by converting video into space–time still images 

    Sala Sanmartí, Marcel; Soriguera Martí, Francesc; Huillca, Kevin; Vilaplana Besler, Verónica (2019-06)
    Article
    Open Access
    Empirical data is needed in order to extend our knowledge of traffic behavior. Video recordings are used to enrich typical data from loop detectors. In this context, data extraction from videos becomes a challenging task. ...

    Article
    Open Access
    This manuscript describes the Microwave Interferometric Reflectometer (MIR) instrument, a multi-beam dual-band GNSS-Reflectometer with beam-steering capabilities built to assess the performance of a PAssive Reflectrometry ...
  • Correspondence matching in unorganized 3D point clouds using Convolutional Neural Networks 

    Pujol Miró, Alba; Casas Pla, Josep Ramon; Ruiz Hidalgo, Javier (2019-03-08)
    Article

    This document presents a novel method based in Convolutional Neural Networks (CNN) to obtain correspondence matchings between sets of keypoints of several unorganized 3D point cloud captures, independently of the sensor ...
  • Depth estimation and semantic segmentation from a single RGB image using a hybrid convolutional neural network 

    Lin, Xiao; Sánchez Escobedo, Dalila; Casas Pla, Josep Ramon; Pardàs Feliu, Montse (Multidisciplinary Digital Publishing Institute (MDPI), 2019-04-15)
    Article
    Open Access
    Semantic segmentation and depth estimation are two important tasks in computer vision, and many methods have been developed to tackle them. Commonly these two tasks are addressed independently, but recently the idea of ...
  • Architectural optimization framework for earth-observing heterogeneous constellations : marine weather forecast case 

    Araguz López, Carles; Llaveria Godoy, David; Lancheros Sepulveda, Estefany Maria; Bou Balust, Elisenda; Camps Carmona, Adriano José; Alarcón Cot, Eduardo José; Tonetti, Stefania; Cornara, Stefania; Vicario, Gonzalo; Lluch i Cruz, Ignasi; Matevosyan, Hripsime; Golkar, Alessandro; Cote, Judith; Pierotti, Stéphane; Rodríguez, Pedro; Alvaro Sanchez, A.; Sochacki, Mateusz; Narkiewicz, Janusz (2019-01-25)
    Article
    Open Access
    Earth observation satellite programs are currently facing, for some applications, the need to deliver hourly revisit times, subkilometric spatial resolutions, and near-real-time data access times. These stringent requirements, ...
  • L-band vegetation optical depth seasonal metrics for crop yield assessment 

    Chaparro Danon, David; Piles Guillem, Maria; Vall-Llossera Ferran, Mercedes Magdalena; Camps Carmona, Adriano José; Konings, Alexandra G.; Entekhabi, Dara (2018-06-01)
    Article

    This article introduces the incorporation of acoustic sensors for the localization of a mobile robot. The robot is considered as a sound source and its position is located applying a Time Delay of Arrival (TDOA) method. ...
  • Spatial mode detection by frequency upconversion 

    Sephton, Bereneice; Vallés Marín, Adam; Steinlechner, Fabian; Konrad, Thomas; Pérez Torres, Juan; Roux, Filippus S.; Forbes, Andrew (2019-02-01)
    Article
    Open Access
    The efficient creation and detection of spatial modes of light has become topical of late, driven by the need to increase photon bit-rates in classical and quantum communications. Such mode creation/detection is traditionally ...
  • Tutorial on remote sensing using GNSS bistatic radar of opportunity 

    Zavorotny, Valery U.; Gleason, Scott; Cardellach Galí, Estel; Camps Carmona, Adriano José (Institute of Electrical and Electronics Engineers, 2014-12)
    Article
