    • BlenderCAVE: Easy VR Authoring for Multi-Screen Displays 

      Gascón, Jorge; Bayona, José M.; Espadero, José M.; Otaduy, Miguel A. (The Eurographics Association, 2021)
      BlenderCave is a framework for the fast creation of virtual reality applications for multi-screen display systems. It consists of a set of extensions to the open-source Blender Game Engine (BGE), leveraging the scene ...

    • A Colour Rotation Based Detector for Bleeding Gastric Pathologies 

      Coelho, P.; Cunha, A.; Costa, P.; Hadjileontiadis, L. (The Eurographics Association, 2021)
      Colour is one the distinct features in computer vision systems and can be represented in several colour spaces. The most commonly used is the RGB colour space, since most high-quality cameras used in computer vision systems ...

    • Graph-Based Reflectance Segmentation 

      Garces, Elena; Gutierrez, Diego; Lopez-Moreno, Jorge (The Eurographics Association, 2021)
      Most of the unsupervised image segmentation algorithms use just RGB color information in order to establish the similarity criteria between pixels in the image. This leads in many cases to a wrong interpretation of the ...

    • GraphJudge: A System for Assisted Assessment of Computer Graphics Assignments 

      Rocha, Lindomar; Rodrigues, Rui (The Eurographics Association, 2021)
      We describe a system for submission, automated validation and assisted evaluation of Computer Graphics' assignments. This type of assessments has a series of specific challenges associated to it, namely the analysis of ...

    • Interactive Visualizations of Automatic Debugging Reports 

      Riboira, André; Rodrigues, Rui; Abreu, Rui (The Eurographics Association, 2021)
      Automated debugging techniques, based on statistical analysis of historical test executions data, have recently received considerable attention due to their diagnostic capabilities. However, current automatic debugging ...

    • 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. ...

    • 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 ...

    • Mobile Computational Photography: Exposure Fusion on the Nokia N900 

      Echevarria, Jose I.; Gutierrez, Diego (The Eurographics Association, 2021)
      This paper explores the Nokia N900 platform as a versatile playground for mobile computational photography. We present the implementation of a simple yet practical application to acquire high quality tone mapped HDR images, ...
