External Forces Guided Fluid Surface and Volume Reconstruction from Monocular Video
(The Eurographics Association, 2019)We propose a novel method to reconstruct fluid's volume movement and surface details from just a monocular video for the first time. Although many monocular video-based reconstruction methods have been developed, the ... -
External Labeling Techniques: A Taxonomy and Survey
(The Eurographics Association and John Wiley & Sons Ltd., 2019)External labeling is frequently used for annotating features in graphical displays and visualizations, such as technical illustrations, anatomical drawings, or maps, with textual information. Such a labeling connects ... -
External Memory View-Dependent Simplification
(Blackwell Publishers Ltd and the Eurographics Association, 2000)In this paper, we propose a novel external-memory algorithm to support view-dependent simplification for datasets much larger than main memory. In the preprocessing phase, we use a new spanned sub-meshes simplification ... -
Extracción Adaptativa de Isosuperficies Topológicamente Correctas
(The Eurographics Association, 2009)Este trabajo propone un nuevo esquema de representación de volúmenes basado en una partición del espacio en poliedros multirresolución, y un método de extracción de isosuperficies sin elementos no-variedad a partir del ... -
Extracting and Visualizing Uncertainties in Segmentations from 3D Medical Data
(The Eurographics Association, 2014)Assessing surfaces of segmentations extracted from 3D image data for medical purposes requires dedicated extraction and visualization methods. In particular, when assessing follow-up cases, the exact volume and confidence ... -
Extracting Boundary Surface of Arbitrary Topology from Volumetric Datasets
(The Eurographics Association, 2001)This paper presents a novel, powerful reconstruction algorithm that can recover correct shape geometry as well as its unknown topology from arbitrarily complicated volumetric datasets. The algorithm starts from a simple ... -
Extracting contour lines from a hierarchical surface model
(Blackwell Science Ltd and the Eurographics Association, 1993)The Hierarchical Triangulated Irregular Network (HTIN) is a structure for representing 2?-dimensional surfaces at different levels of detail through piecewise-linear approximations based on triangulations of the surface ... -
Extracting Features from Time-Dependent Vector Fields Using Internal Reference Frames
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Extracting features from complex, time-dependent flow fields remains a significant challenge despite substantial research efforts, especially because most flow features of interest are defined with respect to a given ... -
Extracting Flow Structures Using Sparse Particles
(The Eurographics Association, 2011)In recent years, Lagrangian Coherent Structures (LCS) have been characterized using the Finite-Time Lyapunov Exponent, following the advection of a dense set of particles into a corresponding flow field. The large amount ... -
Extracting Jacobi Structures in Reeb Spaces
(The Eurographics Association, 2014)Jacobi sets have been identified as significant in multi-field topological analysis, but are defined in the domain ofthe data rather than in the Reeb Space. This distinction is significant, as exploiting multi-field topology ... -
EXTRACTING LINE MAPS FROM IMAGES
(The Eurographics Association, 1981)We present methods to vectorize automatically information given in raster form, the algorithms used are discussed briefly, and results for some test cases are presented. The compression of information is discussed as well ... -
Extracting Microfacet-based BRDF Parameters from Arbitrary Materials with Power Iterations
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We introduce a novel fitting procedure that takes as input an arbitrary material, possibly anisotropic, and automatically converts it to a microfacet BRDF. Our algorithm is based on the property that the distribution of ... -
Extracting Ordered Iso-Geodesic Points on the Mesh
(The Eurographics Association, 2020)The mesh manifold is one of the most used modalities for representing 3D objects. Although it provides a fully connected not oriented structure, it has some drawback when compared to the grid of pixels of a still image. ... -
Extracting Sharp Features from RGB‐D Images
(© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)Sharp edges are important shape features and their extraction has been extensively studied both on point clouds and surfaces. We consider the problem of extracting sharp edges from a sparse set of colour‐and‐depth (RGB‐D) ... -
Extracting the Essence from Sets of Images
(The Eurographics Association, 2007)We use a set of photographs showing similar scenes as a model for a single photograph this scene. A distance measure for this model is defined by correlating the neigborhoods of pixels in similar positions. A cross analysis ... -
Extracting, Visualizing and Tracking Mesoscale Ocean Eddies in Two-dimensional Image Sequences Using Contours and Moments
(The Eurographics Association, 2017)We introduce a system to extract and track mesoscale eddies captured in massive global ocean simulations. The major strength and contribution of our system is its design, which is based on two-dimensional image data ... -
Extraction and Organization of Form Features into a Structured Boundary Model
(Eurographics Association, 1987)A method is presented for the automatic identification and extraction of feature information from the solid model of an object. The procedure consists of recognizing shape features, extracting those features as solid volumes ... -
Extraction and Simplification of Iso-surfaces in Tandem
(The Eurographics Association, 2005)The tandem algorithm combines the marching cube algorithm for surface extraction and the edge contraction algorithm for surface simplification in lock-step to avoid the costly intermediate step of storing the entire extracted ... -
Extraction and Transfer of Facial Expression Wrinkles for Facial Performance Enhancement
(The Eurographics Association, 2014)Creating realistic models and animations of human faces with adequate level of detail is very challenging due to the high complexity of facial deformations and the sensitivity of the human visual system to human faces. One ... -
Extraction and Visual Analysis of Seismic Horizon Ensembles
(The Eurographics Association, 2013)Seismic interpretation is an important step in building subsurface models, which are needed to efficiently exploit fossil fuel reservoirs. However, seismic features are seldom unambiguous, resulting in a high degree of ...
