    Although online e-learning environments are increasingly used in university courses, manual assessment still dominates the way students are graded. Interactive judges providing a pass/fail verdict based on test sets are ...
  • A virtual reality front-end for city modeling 

    Randó Segura, Eduard; Andújar Gran, Carlos Antonio; Patow, Gustavo Ariel (European Association for Computer Graphics (Eurographics), 2019)
    Conference lecture
    Open Access
    Current tools for city modeling, including those supporting procedural techniques, have a steep learning curve and require substantial user input and/or skills to create realistic 3D models of cities. In this paper we ...
  • Effective visualization of sparse image-to-image correspondences 

    Andújar Gran, Carlos Antonio; Chica Calaf, Antonio; Comino Trinidad, Marc (European Association for Computer Graphics (Eurographics), 2020)
    Conference report
    Open Access
    Finding robust correspondences between images is a crucial step in photogrammetry applications. The traditional approach to visualize sparse matches between two images is to place them side-by-side and draw link segments ...
  • A Tool for N-way analysis of programming exercises 

    Andújar Gran, Carlos Antonio; Comino Trinidad, Marc; Fairén González, Marta; Vinacua Pla, Álvaro (European Association for Computer Graphics (Eurographics), 2020)
    Conference report
    Open Access
    Programming exercises are a corner stone in Computer Science courses. If used properly, these exercises provide valuable feedback both to students and instructors. Unfortunately, the assessment of student submissions through ...
  • Multilingual, multi-scale and multi-layer visualization of sequence-based intermediate representations

    The main alternatives nowadays to dealwith sequences are Recurrent Neural Net-works (RNN), Convolutional Neural Networks(CNN) architectures and the Transformer. Inthis context, RNN’s, CNN’s and Transformerhave most commonly ...
  • Multi-view image fusion 

    Comino Trinidad, Marc; Martin Brualla, Ricardo; Kainz, Florian; Kontkanen, Janne (2019)
    Conference report
    Open Access
    We present an end-to-end learned system for fusing multiple misaligned photographs of the same scene into a chosen target view. We demonstrate three use cases: 1) color transfer for inferring color for a monochrome view, ...
  • MeshPipe: a Python-based tool for easy automation and demonstration of geometry processing pipelines 

    Fons Sánchez, Joan; Chica Calaf, Antonio; Andújar Gran, Carlos Antonio (Scitepress, 2020)
    Conference report
    Open Access
    The popularization of inexpensive 3D scanning, 3D printing, 3D publishing and AR/VR display technologies have renewed the interest in open-source tools providing the geometry processing algorithms required to clean, repair, ...
  • View-dependent hierarchical rendering of massive point clouds through textured splats 

    Comino Trinidad, Marc; Chica Calaf, Antonio; Andújar Gran, Carlos Antonio (European Association for Computer Graphics (Eurographics), 2019)
    Conference report
    Open Access
    Nowadays, there are multiple available range scanning technologies which can capture extremely detailed models of realworld surfaces. The result of such process is usually a set of point clouds which can contain billions ...
  • Smooth transitioning between two walking metaphors for virtual reality applications 

    Salvetti, Isadora; Ríos Jerez, 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)
