Natural Image Colorization
(The Eurographics Association, 2007)In this paper, we present an interactive system for users to easily colorize the natural images of complex scenes. In our system, colorization procedure is explicitly separated into two stages: Color labeling and Color ... -
Natural Interaction in Asymmetric Teleconference using Stuffed-toy Avatar Robot
(The Eurographics Association, 2016)In this paper, we propose an asymmetric teleconference system using stuffed-toy robot as the representative of the remote user. Our main goal is to realize the system that can provide natural conversation both on the remote ... -
Natural Lighting, Gilts and Polychromy of Notre-Dame de Paris Cathedral
(The Eurographics Association, 2010)Lighting either natural or not in the european medieval architecture (roman period) is studied and simulated around a special and famous example. "Notre-Dame de Paris" cathedral and its polychromy are studied for many years ... -
Natural Visualizations
(The Eurographics Association, 2006)This paper demonstrates the prevalence of a shared characteristic between visualizations and images of nature. We have analyzed visualization competitions and user studies of visualizations and found that the more preferred, ... -
Navigation and Exploration of Interconnected Pathways
(The Eurographics Association and Blackwell Publishing Ltd., 2008)Visualizing pathways, i. e. models of cellular functional networks, is a challenging task in computer assisted biomedicine. Pathways are represented as large collections of interwoven graphs, with complex structures present ... -
Näprä - Affordable Fingertip Tracking with Ultrasound
(The Eurographics Association, 2005)In this paper we present Näprä, a novel tracking device suitable for fine motor interaction. The motivation for building the device was the need to track users' fingertips in an immersive free-hand drawing environment. ... -
Near Light Correction for Image Relighting and 3D Shape Recovery
(IEEE, 2015)In this paper, we propose a near-light illumination model for image relighting and 3D shape recovery. Classic methods such as used by the popular RTI software from Cultural Heritage Imaging assume that lighting is infinitely ... -
Near Optimal Hierarchical Culling: Performance Driven Use of Hardware Occlusion Queries
(The Eurographics Association, 2006)The most efficient general occlusion culling techniques are based on hardware accelerated occlusion queries. Although in many cases these techniques can considerably improve performance, they may still reduce efficiency ... -
Near-Isometric Level Set Tracking
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Implicit representations of geometry have found applications in shape modeling, simulation, and other graphics pipelines. These representations, however, do not provide information about the paths of individual points as ... -
Nearly Recurrent Components in 3D Piecewise Constant Vector Fields
(The Eurographics Association and Blackwell Publishing Ltd., 2012)We present an algorithm for computing nearly recurrent components, that represent areas of close to circulating or stagnant flow, for 3D piecewise constant (PC) vector fields defined on regular grids. Using a number of ... -
Neatening sketched strokes using piecewise French Curves
(The Eurographics Association, 2011)We apply traditional bimanual curve modeling using French curves to the problem of automatic neatening of sketched strokes. Given a sketched input stroke and a set of template French curves we present an approach that fits ... -
Neon: A Single-Chip 3D Workstation Graphics Accelerator
(The Eurographics Association, 1998)High-performance 3D graphics accelerators traditionally require multiple chips on multiple boards, including geometry, rasterizing, pixel processing, and texture mapping chips. These designs are often scalable: they can ... -
NeRF for 3D Reconstruction from X-ray Angiography: Possibilities and Limitations
(The Eurographics Association, 2023)Neural Radiance Field (NeRF) is a promising deep learning technique based on neural rendering for three-dimensional (3D) reconstruction. This technique has overcome several limitations of 3D reconstruction techniques, such ... -
Networked Displays for VR Applications: Display as a Service
(The Eurographics Association, 2012)Stereoscopic Liquid Crystal Displays (LCDs) in a tiled setup, so-called display walls, are rising as a replacement for the classic projection-based systems for Virtual Reality (VR) applications. They have numerous benefits ... -
Networks of Names: Visual Exploration and Semi-Automatic Tagging of Social Networks from Newspaper Articles
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Understanding relationships between people and organizations by reading newspaper articles is difficult to manage for humans due to the large amount of data. To address this problem, we present and evaluate a new visual ... -
Neural Appearance Synthesis and Transfer
(The Eurographics Association, 2019)Appearance acquisition is a challenging problem. Existing approaches require expensive hardware and acquisition times are long. Alternative ''in-the-wild'' few-shot approaches provide a limited reconstruction quality. ... -
Neural Correlates of Disrupted Presence: Strange Disruptions in a Naturalistic Virtual Environment
(The Eurographics Association, 2014)The concept of presence is commonly related to whether or not a user feels, acts, and reacts as if he/she were in a real familiar environment when using a virtual reality (VR) application. Understanding the neural correlates ... -
Neural Deformable Cone Beam CT
(The Eurographics Association, 2023)In oral and maxillofacial cone beam computed tomography (CBCT), patient motion is frequently observed and, if not accounted for, can severely affect the usability of the acquired images. We propose a highly flexible, data ... -
Neural Denoising for Path Tracing of Medical Volumetric Data
(ACM, 2020)In this paper, we transfer machine learning techniques previously applied to denoising surface-only Monte Carlo renderings to path-traced visualizations of medical volumetric data. In the domain of medical imaging, path-traced ... -
Neural Intersection Function
(The Eurographics Association, 2023)The ray casting operation in the Monte Carlo ray tracing algorithm usually adopts a bounding volume hierarchy (BVH) to accelerate the process of finding intersections to evaluate visibility. However, its characteristics ...
