Uncertainty-aware Visualization of Regional Time Series Correlation in Spatio-temporal Ensembles
(The Eurographics Association and John Wiley & Sons Ltd., 2021)Given a time-varying scalar field, the analysis of correlations between different spatial regions, i.e., the linear dependence of time series within these regions, provides insights into the structural properties of the ... -
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 ... -
Uncut Aerial Video via a Single Sketch
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Nowadays UAV filming is getting popular, more and more stunning aerial videos appearing online. Nonetheless, making a good uncut aerial video with only one-long-shot for the large-scale outdoor scenes is still quite ... -
UnderPressure: Deep Learning for Foot Contact Detection, Ground Reaction Force Estimation and Footskate Cleanup
(The Eurographics Association and John Wiley & Sons Ltd., 2022)Human motion synthesis and editing are essential to many applications like video games, virtual reality, and film postproduction. However, they often introduce artefacts in motion capture data, which can be detrimental to ... -
Undersampled Light Field Rendering by a Plane Sweep
(The Eurographics Association and Blackwell Publishing Ltd, 2006)Images synthesized by light field rendering exhibit aliasing artifacts when the light field is undersampled; adding new light field samples improves the image quality and reduces aliasing but new samples are expensive to ... -
Understanding and Designing Perceptual Experiments
(The Eurographics Association, 2013)Humans and computer both have limited resources with which they must process the massive amount of information present in the natural world. For over 150 years, physiologists and psychologists have been performing experiments ... -
Understanding Business Analysts' Needs for Data Report Authoring
(The Eurographics Association, 2022)Business analysts often create static, data-driven reports to summarize and communicate findings from marketing dashboards. However, the requirements and workflow for creating data-driven reports in business analytics have ... -
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 Exposure for Reverse Tone Mapping
(The Eurographics Association, 2008)High dynamic range (HDR) displays are capable of providing a rich visual experience by boosting both luminance and contrast beyond what conventional displays can offer.We envision that HDR capture and display hardware will ... -
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 Indirect Causal Relationships in Node-Link Graphs
(The Eurographics Association and John Wiley & Sons Ltd., 2017)To find correlations and cause and effect relationships in multivariate data sets is central in many data analysis problems. A common way of representing causal relations among variables is to use node-link diagrams, where ... -
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 Mystery Behind Example-Based Image Synthesis
(The Eurographics Association, 2018)This tutorial presents a concise overview of development in the field of example-based image synthesis that over the last two decades rapidly evolved into a powerful tool enabling the production of synthetic imagery often ... -
Understanding Networks beyond Overlapping Clusters
(The Eurographics Association, 2016)Tasks associated with the investigation of large complex clustered networks are widespread in various research areas. Among the popular and common approaches to exploratory analysis, it is definitely worthwhile to underscore ... -
Understanding Spatial Perception and Visual Modes in the Review of Architectural Designs
(ACM, 2017)We investigate how a person's perception of space in di erent visual modes relates to common computational spatial measures for environment designs. The three spatial measures, grounded in Space-Syntax analysis, are used ... -
Understanding the Design Space and Authoring Paradigms for Animated Data Graphics
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Creating expressive animated data graphics often requires designers to possess highly specialized programming skills. Alternatively, the use of direct manipulation tools is popular among animation designers, but these tools ... -
