    • Feasibility of measuring fusional vergence amplitudes objectively 

      Rovira Gay, Cristina; Mestre Ferrer, Clara; Argilés Sans, Marc; Viñuela Navarro, Valldeflors; Pujol Ramo, Jaume (Public Library of Science (PLOS), 2023-05-04)
      Article
      Accés obert
      Two tests to measure fusional vergence amplitudes objectively were developed and validated against the two conventional clinical tests. Forty-nine adults participated in the study. Participants’ negative (BI, base in) and ...

    • A Preliminary study of deep learning sensor fusion for pedestrian detection 

      Chávez Plascencia, Alfredo; García Gómez, Pablo; Bernal Pérez, Eduard; Mas Giménez, Gerard de; Casas Pla, Josep Ramon; Royo Royo, Santiago (Multidisciplinary Digital Publishing Institute (MDPI), 2023-04)
      Article
      Accés obert
      Most pedestrian detection methods focus on bounding boxes based on fusing RGB with lidar. These methods do not relate to how the human eye perceives objects in the real world. Furthermore, lidar and vision can have difficulty ...

    • Membrane protein detection and morphological analysis of red blood cells in hereditary spherocytosis by confocal laser scanning microscopy 

      Rey Barroso, Laura; Roldán Molina, Mónica; Burgos Fernández, Francisco Javier; Isola, Ignacio Mario; Ruiz Llobet, Anna; Gassiot Riu, Susanna; Sarrate Garcia, Edurne; Vilaseca Ricart, Meritxell (2023-04)
      Article
      Accés obert
      In hereditary spherocytosis (HS), genetic mutations in the cell membrane and cytoskeleton proteins cause structural defects in red blood cells (RBCs). As a result, cells are rigid and misshapen, usually with a characteristic ...
