    • HYPERIMAGES - AN ALTERNATIVE TO THE CONVENTIONAL DIGITAL IMAGES 

      Bieri, Hanspeter (Eurographics Association, 1990)
      Hyperimages represent a variation of the conventional digital images which implies pixels of different dimensions within the same image. The extent of a hyperimage is the disjoint union of all pixel extents it contains, ...

    • HyperMoVal: Interactive Visual Validation of Regression Models for Real-Time Simulation 

      Piringer, Harald; Berger, Wolfgang; Krasser, Jürgen (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      Abstract During the development of car engines, regression models that are based on machine learning techniques are increasingly important for tasks which require a prediction of results in real-time. While the validation ...

      Projection algorithms such as t-SNE or UMAP are useful for the visualization of high dimensional data, but depend on hyperparameters which must be tuned carefully. Unfortunately, iteratively recomputing projections to find ...

    • Hyperplane Culling for Stochastic Rasterization 

      Munkberg, Jacob; Akenine-Möller, Tomas (The Eurographics Association, 2012)
      We present two novel culling tests for rasterization of simultaneous depth of field and motion blur. These tests efficiently reduce the set of xyuvt samples that need to be coverage tested within a screen space tile. The ...

      In this paper we present Hypersliceplorer, an algorithm for generating 2D slices of multi-dimensional shapes defined by a simplical mesh. Often, slices are generated by using a parametric form and then constraining parameters ...

    • Hyperspectral Inverse Skinning 

      Liu, Songrun; Tan, Jianchao; Deng, Zhigang; Gingold, Yotam (© 2020 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd, 2020)
      In example‐based inverse linear blend skinning (LBS), a collection of poses (e.g. animation frames) are given, and the goal is finding skinning weights and transformation matrices that closely reproduce the input. These ...

    • A Hyperspectral Space of Skin Tones for Inverse Rendering of Biophysical Skin Properties 

      Aliaga, Carlos; Xia, Mengqi; Xie, Hao; Jarabo, Adrian; Braun, Gustav; Hery, Christophe (The Eurographics Association and John Wiley & Sons Ltd., 2023)
      We present a method for estimating the main properties of human skin, leveraging a hyperspectral dataset of skin tones synthetically generated through a biophysical layered skin model and Monte Carlo light transport ...

    • HyperStreamball Visualization for Symmetric Second Order Tensor Fields 

      Liu, J.; Turner, M.; Hewitt, W. T.; Perrin, J. S. (The Eurographics Association, 2006)
      This paper proposes a new 3D tensor glyph called a hyperstreamball that extends streamball visualization used within fluid flow fields to applications within second order tensor fields. The hyperstreamball is a hybrid of ...

    • I Don't Believe My Eyes! Geometric Sketch Recognition for a Computer Art Tutorial 

      Cummmings, Danielle; Vides, Francisco; Hammond, Tracy (The Eurographics Association, 2012)
      Drawing is a common form of communication and a means of artistic expression. Many of us believe that the ability to draw accurate representations of objects is a skill that either comes naturally or is the result of hours ...

    • The i-Disc - A Tool To Visualize and Explore Topic Maps 

      Hofmann, Tobias; Wendler, Hendrik; Froehlich, Bernd (The Eurographics Association, 2005)
      We present the i-Disc, a tool to interactively visualize and explore medium sized topic maps. Topic maps contain two basic structures: the topic hierarchy and the associations between topics. Our system presents the topic ...

    • I-SI: Scalable Architecture of Analyzing Latent Topical-Level Information From Social Media Data 

      Wang, Xiaoyu; Dou, Wenwen; Ma, Zhiqiang; Villalobos, Jeremy; Chen, Yang; Kraft, Thomas; Ribarsky, William (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      We present a general visual analytics architecture that is designed and implemented to effectively analyze unstructured social media data on a large scale. Pipelined on a high-performance cluster configuration, MPI processing, ...

    • I-UsE: Integrated Usability Evaluation Environment 

      Marcelino, Luís; Amaral, Vasco (The Eurographics Association, 2021)
      Software usability evaluation (UE) is a typically neglected phase by software developers. Due to the high costs of properly done formal usability studies, companies easily cut investment, contributing deliberately to the ...

    • The I.M.O.G.E.N .E. Machine: Some Hardware Elements 

      Lefevere, V.; Karpf, S.; Chaillou, C.; Meriaux, M. (The Eurographics Association, 1991)
      The goal of the I.M.O.G.E.N.E. project is to define a real time graphics system. We focus on true real time display, images being computed at frame rate, i.e 50 (or 60) times a second. The I.M.O.G.E.N.E. machine uses no ...
