      Article
      Open Access
      Personality analysis has been widely studied in psychology, neuropsychology, and signal processing fields, among others. From the past few years, it also became an attractive research area in visual computing. From the ...
    • Smooth transitioning between two walking metaphors for virtual reality applications 

      Salvetti, Isadora; Ríos Jérez, Alejandro; Pelechano Gómez, Núria (European Association for Computer Graphics (Eurographics), 2019)
      Conference report
      Open Access
      Virtual navigation should be as similar as possible to how we move in the real world, however the limitations of hardware and physical space make this a challenging problem. Tracking natural walk is only feasible when the ...
    • A Web-based application for the visual exploration of colon morphology data 

      Males, Jan; Monclús Lahoya, Eva; Díaz Iriberri, José; Vázquez Alcocer, Pere Pau (European Association for Computer Graphics (Eurographics), 2019)
      Conference report
      Open Access
      The colon is an organ whose constant motility poses difficulties to its analysis. Although morphological data can be successfully extracted from Computational Tomography, its radiative nature makes it only indicated for ...
    • Colonic content assessment from MRI imaging using a semi-automatic approach 

      Ceballos Inza, Víctor; Monclús Lahoya, Eva; Vázquez Alcocer, Pere Pau; Bendezú García, Álvaro; Mego Silva, Marianela; Merino Casabiel, Xavier; Azpiroz Vidaur, Fernando; Navazo Álvaro, Isabel (European Association for Computer Graphics (Eurographics), 2019)
      Conference report
      Open Access
      The analysis of the morphology and content of the gut is necessary in order to achieve a better understanding of its metabolic and functional activity. Magnetic resonance imaging (MRI) has become an important imaging ...
    • An automatic tool to facilitate authoring animation blending in game engines 

      Delicado Alcántara, Luis; Pelechano Gómez, Núria (Association for Computing Machinery (ACM), 2019)
