  • Investigating the Differences Between European Portuguese Sounds: An Approach Using Polygonal Mesh Comparison 

    Martins, Paula; Silva, Samuel; Oliveira, Catarina; Ferreira, Carlos; Silva, Augusto; Teixeira, António (The Eurographics Association, 2021)
    With the main purpose of studying the articulatory configuration of the European Portuguese (EP) sounds and to evaluate coarticulatory effects, a large 3D MRI database from several speakers and contexts have been acquired. ...
  • Robust Method for Estimating Normals on Point Clouds Using Adaptive Neighborhood Size 

    Leal, E.A.; Leal, N.E. (The Eurographics Association, 2021)
    Normal estimation on sampled curves or surfaces is a basic step of many algorithms in computer graphics, computer vision, and especially in recognition and reconstruction of three dimensional objects. This paper presents ...
  • Left-Ventricle Global and Regional Functional Analysis from MDCT Images 

    Silva, Samuel; Santos, Beatriz Sousa; Madeira, Joaquim (The Eurographics Association, 2021)
    Left-ventricle functional analysis is of paramount importance for the assessment of coronary artery disease. Non-invasive coronary artery imaging using multiple-detector computed tomography (MDCT) provides a wealth of data ...

  • Interactive Elastic Deformation of 3D Images 

    Prados, Francisco J. R.; Salas, Alejandro León; Torres, Juan Carlos (The Eurographics Association, 2021)
    The standard workflow of a haptic device takes the position of the effector in space and sends a force vector in return. This paradigm naturally meets the behaviour shown in elastic materials, where the resistant force of ...

  • Parallel Collision Detection Oriented to Distributed Memory Architectures for High-Resolution Meshes 

    Novalbos, Marcos; Sánchez, Alberto (The Eurographics Association, 2021)
    Higher resolution meshes should be used in graphics applications to make them as realistic as they can. However, they imply a high computational. Several approaches have been built to solve collision detection, although ...
