UberFlow: A GPU-Based Particle Engine
(The Eurographics Association, 2004)We present a system for real-time animation and rendering of large particle sets using GPU computation and memory objects in OpenGL. Memory objects can be used both as containers for geometry data stored on the graphics ... -
UDMV 2016: Frontmatter
(Eurographics Association, 2016) -
UI-Net: Interactive Artificial Neural Networks for Iterative Image Segmentation Based on a User Model
(The Eurographics Association, 2017)For complex segmentation tasks, fully automatic systems are inherently limited in their achievable accuracy for extracting relevant objects. Especially in cases where only few data sets need to be processed for a highly ... -
Ultrasound Decompression for Large Field-of-View Reconstructions
(The Eurographics Association, 2018)Tracked medical ultrasound allows for cost-effective and radiation-free imaging of anatomy featuring a very high spatial resolution. To overcome the limitations of the small field-of-view, sonographers can acquire multiple ... -
Uncertainty and Variability in Point Cloud Surface Data
(The Eurographics Association, 2004)We present a framework for analyzing shape uncertainty and variability in point-sampled geometry. Our representation is mainly targeted towards discrete surface data stemming from 3D acquisition devices, where a finite ... -
Uncertainty Estimation and Visualization for Multi-modal Image Segmentation
(The Eurographics Association, 2015)Multi-modal imaging allows for the integration of complementary information from multiple medical imaging modalities for an improved analysis. The multiple information channels may lead to a reduction of the uncertainty ... -
Uncertainty-aware Brain Lesion Visualization
(The Eurographics Association, 2020)A brain lesion is an area of tissue that has been damaged through injury or disease. Its analysis is an essential task for medical researchers to understand diseases and find proper treatments. In this context, visualization ... -
Uncertainty-aware Ensemble of Classifiers for Segmenting Brain MRI Data
(The Eurographics Association, 2014)Estimating and visualizing uncertainty in medical image segmentation has become an active research area due to the necessity of making medical experts aware of possibly wrong segmentation decisions. Still, to our knowledge ... -
Uncertainty-Aware Exploration of Continuous Parameter Spaces Using Multivariate Prediction
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Systems projecting a continuous n-dimensional parameter space to a continuous m-dimensional target space play an important role in science and engineering. If evaluating the system is expensive, however, an analysis is ... -
Uncertainty-Guided Semi-Automated Editing of CNN-based Retinal Layer Segmentations in Optical Coherence Tomography
(The Eurographics Association, 2018)Convolutional neural networks (CNNs) have enabled dramatic improvements in the accuracy of automated medical image segmentation. Despite this, in many cases, results are still not reliable enough to be trusted ''blindly''. ... -
Unconditionally Stable Shock Filters for Image and Geometry Processing
(The Eurographics Association and John Wiley & Sons Ltd., 2015)This work revisits the Shock Filters of Osher and Rudin [OR90] and shows how the proposed filtering process can be interpreted as the advection of image values along flow-lines. Using this interpretation, we obtain an ... -
Unconstrained Isosurface Extraction on Arbitrary Octrees
(The Eurographics Association, 2007)This paper presents a novel algorithm for generating a watertight level-set from an octree. We show that the level- set can be efficiently extracted regardless of the topology of the octree or the values assigned to the ... -
Uncovering Representative Groups in Multidimensional Projections
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Multidimensional projection-based visualization methods typically rely on clustering and attribute selection mechanisms to enable visual analysis of multidimensional data. Clustering is often employed to group similar ... -
Understanding City Dynamics through Spatio-temporal Visualization
(The Eurographics Association, 2013)Every time we visit a new city there is a huge effort made in understanding its dynamic, i.e. what are the relevant locations within that city in each time period, for there are large amounts of data to sift through. ... -
Understanding Graph Convolutional Networks to detect Brain Lesions from Stroke
(The Eurographics Association, 2022)Brain lesions derived from stroke episodes can result in disabilities for a patient. Therefore, the segmentation of brain lesions is an important task in neurology. Recently this task has been mainly tackled by machine ... -
Understanding Interactive Legends: a Comparative Evaluation with Standard Widgets
(The Eurographics Association and Blackwell Publishing Ltd., 2010)Interactive information visualization systems rely on widgets to allow users to interact with the data and modify the representation. We define interactive legends as a class of controls combining the visual representation ... -
Understanding the Efficiency of GPU Algorithms for Matrix-Matrix Multiplication
(The Eurographics Association, 2004)Utilizing graphics hardware for general purpose numerical computations has become a topic of considerable interest. The implementation of streaming algorithms, typified by highly parallel computations with little reuse of ... -
Understanding the Efficiency of Ray Traversal on GPUs
(The Eurographics Association, 2009)We discuss the mapping of elementary ray tracing operations- acceleration structure traversal and primitive intersection-onto wide SIMD/SIMT machines. Our focus is on NVIDIA GPUs, but some of the observations should be ... -
Understanding the Impact of Statistical and Machine Learning Choices on Predictive Models for Radiotherapy
(The Eurographics Association, 2022)During radiotherapy (RT) planning, an accurate description of the location and shape of the pelvic organs is a critical factor for the successful treatment of the patient. Yet, during treatment, the pelvis anatomy may ... -
Underwater photogrammetry for archaeology and marine biology.40 years of experience in Marseille, France
