      En los últimos años las técnicas de aprendizaje profundo se han convertido en una poderosa alternativa a técnicas clásicas de aprendizaje automático orientadas a tareas de clasificación. Esta tecnología se ha aplicado con ...
    • Kernel-Based Sampling of Arbitrary Data 

      Cammarasana, Simone; Patanè, Giuseppe (The Eurographics Association, 2020)
      Point sampling is widely used in several Computer Graphics' applications, such as point-based modelling and rendering, image and geometric processing. Starting from the kernel-based sampling of signals defined on a regular ...
    • Kernel-Reflection Sequences 

      Szécsi, László; Bendefy, Zoltán; Kacsó, Ágota (The Eurographics Association, 2016)
      Complex geometries, like those of plants, rocks, terrain, or even clouds are challenging to model in a way that allows for real-time rendering but does not make concessions in terms of visible detail. In this paper we ...
    • Keyframing Particles of Physically Based Systems 

      Dingle, Brent M.; Keyser, John (The Eurographics Association, 2005)
      This paper will present a way to use keyframing methods for particle motion to enhance the visual effects and user controllability of physically based particle systems. This will be done using an adaptive correction ...
