    • Augmented Reality for Web - A New Interaction Method Without Markers 

      Silva, Luis F. A.; Silva, Frutuoso G. M. (The Eurographics Association, 2021)
      In the new age of omnipresent internet, browsers are accessible on every device in everyday's life. Thus it is also needed new interaction methods to facilitate the interaction through browser. Augmented reality is one 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 ...

    • 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 ...

    • Interacting with Outdoor Sports Performance Data 

      Lopes, J. M. Brisson (The Eurographics Association, 2021)
      This paper presents a portable application to visualize performance data obtained from GPS devices in outdoor sports (e.g., ski, running, BTT) that also record data as heartbeat rate. GPS file formats are analyzed and a ...

    • 3D Visualization of Sparse Geophysical Data Representing Uncertainty 

      Gonçalves, Vítor; Dias, Paulo; Almeida, Fernando; Madeira, Joaquim; Santos, Beatriz Sousa (The Eurographics Association, 2021)
      Geophysical data are sparse and by nature difficult to analyze. Usually domain experts use "mental models" to infer missing data according to the surrounding data and their own knowledge. The main goal of this work is to ...

    • A Moving Least Squares Method for Implant Model Deformation in Computer Aided Orthopedic Surgery for Fractures of Lower Extremities 

      Ramírez, Esmitt; Coto, Ernesto (The Eurographics Association, 2021)
      Preoperative planning is an essential step before performing any surgical procedure. Computer Aided Orthopedic Surgery (CAOS) systems are extensively used for the planning of surgeries for fractures of lower extremities. ...

    • High-quality Compression of Mipmapped Textures 

      Andujar, C. (The Eurographics Association, 2021)
      High-quality texture minification techniques, including trilinear and anisotropic filtering, require texture data to be arranged into a collection of prefiltered texture maps called mipmaps. In this paper we present a ...

    • Procedural Modeling of Suspension Bridges 

      Patow, Gustavo (The Eurographics Association, 2021)
      In this paper we introduce a method for designing a class of engineering structures, namely suspension bridges. These bridges are ubiquitous in the industrialized countries, often appearing in known city landscapes, yet ...

    • Volume-Surface Collision Detection 

      Ortegano, J.; Navarro, H.; Carmona, R. (The Eurographics Association, 2021)
      The presence or not of collisions between objects is usually required to study the interaction between them, increasing the realism in virtual environments. Collision detection between polygonal objects has been widely ...

    • Cortical 3D Face Recognition Framework 

      Rodrigues, J.; Lam, R.; Buf, J. du (The Eurographics Association, 2021)
      Empirical studies concerning face recognition suggest that faces may be stored in memory by a few canonical representations. In cortical area V1 exist double-opponent colour blobs, also simple, complex and end-stopped cells ...

    • 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, ...

    • 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 ...

    • Proceedings Info 

      Silva, F.; Gutierrez, D.; Rodríguez, J.; Figueiredo, M. (Eurographics Association, 2021-06-15)
