      Deep learning is increasingly used in the field of glaucoma research. Although deep learning models can achieve high accuracy, issues with trust, interpretability, and practical utility form barriers to adoption in clinical ...

    • Glare Generation Based on Wave Optics 

      Kakimoto, Masanori; Matsuoka, Kaoru; Nishita, Tomoyuki; Naemura, Takeshi; Harashima, Hiroshi (The Eurographics Association and Blackwell Publishing Ltd., 2005)
      This paper proposes a novel and general method of glare generation based on wave optics. A glare image is regarded as a result of Fraunhofer diffraction, which is equivalent to a 2D Fourier transform of the image of given ...

    • GlassNet: Label Decoupling‐based Three‐stream Neural Network for Robust Image Glass Detection 

      Zheng, Chengyu; Shi, Ding; Yan, Xuefeng; Liang, Dong; Wei, Mingqiang; Yang, Xin; Guo, Yanwen; Xie, Haoran (© 2022 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd, 2022)
      Most of the existing object detection methods generate poor glass detection results, due to the fact that the transparent glass shares the same appearance with arbitrary objects behind it in an image. Different from ...

    • glGA: an OpenGL Geometric Application Framework for a Modern, Shader-based Computer Graphics Curriculum 

      Papagiannakis, George; Papanikolaou, Petros; Greassidou, Elisavet; Trahanias, Panos (The Eurographics Association, 2014)
      This paper presents the open-source glGA (Opengl Geometric Application) framework, a lightweight, shaderbased, comprehensive and easy to understand computer graphics (CG) teaching C++ system that is used for educational ...

    • Glint Rendering based on a Multiple-Scattering Patch BRDF 

      Chermain, Xavier; Claux, Frédéric; Mérillou, Stéphane (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      Rendering materials such as metallic paints, scratched metals and rough plastics requires glint integrators that can capture all micro-specular highlights falling into a pixel footprint, faithfully replicating surface ...

    • Global and Local Mesh Morphing for Complex Biological Objects from µCT Data 

      Knötel, David; Becker, Carola; Scholtz, Gerhard; Baum, Daniel (The Eurographics Association, 2018)
      We show how biologically coherent mesh models of animals can be created from µCT data to generate artificial yet naturally looking intermediate objects. The whole pipeline of processing algorithms is presented, starting ...

    • Global Conformal Surface Parameterization 

      Gu, Xianfeng; Yau, Shing-Tung (The Eurographics Association, 2003)
      We solve the problem of computing global conformal parameterizations for surfaces with nontrivial topologies. The parameterization is global in the sense that it preserves the conformality everywhere except for a few points, ...

    • Global Consistency in the Automatic Assembly of Fragmented Artefacts 

      Castañeda, Antonio García; Brown, Benedict; Rusinkiewicz, Szymon; Funkhouser, Thomas; Weyrich, Tim (The Eurographics Association, 2011)
      Automatic reconstruction of fragmented objects is of great interest in archaeology, where artefacts are often found in a fractured state. In this paper, we focus on the problem of automatically agglomerating clusters of ...

    • Global Contrast Factor - a New Approach to Image Contrast 

      Matkovic, Kresimir; Neumann, László; Neumann, Attila; Psik, Thomas; Purgathofer, Werner (The Eurographics Association, 2005)
      Contrast in image processing is usually defined as a ratio between the darkest and the brightest spots of an image. In this paper we introduce a different contrast definition. The newly introduced Global Contrast Factor ...
