A PatchMatch-based Approach for Matte Propagation in Videos
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Despite considerable advances in natural image matting over the last decades, video matting still remains a difficult problem. The main challenges faced by existing methods are the large amount of user input required, and ... -
PatchMove: Patch-based Fast Image Interpolation with Greedy Bidirectional Correspondence
(The Eurographics Association, 2014)In this paper, we present a method for the plausible interpolation of images. This method has several applications, such as for smooth view interpolation, low frame-rate video upsampling, and animation. The central idea ... -
Patent Retrieval: A Multi-Modal Visual Analytics Approach
(The Eurographics Association, 2016)Claiming intellectual property for an invention by patents is a common way to protect ideas and technological advancements. However, patents allow only the protection of new ideas. Assessing the novelty of filed patent ... -
Path differentials and applications
(The Eurographics Association, 2001)Photo-realistic rendering algorithms such as Monte Carlo ray tracing sample individual paths to compute images. Noise and aliasing artefacts are usually reduced by supersampling. Knowledge about the neighborhood of the ... -
Path from Photorealism to Perceptual Realism
(2022-09)Photorealism in computer graphics --- rendering images that appear as realistic as photographs --- has matured to the point that it is now widely used in industry. With emerging 3D display technologies, the next big challenge ... -
Path Guiding Using Spatio‐Directional Mixture Models
(© 2022 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd, 2022)We propose a learning‐based method for light‐path construction in path tracing algorithms, which iteratively optimizes and samples from what we refer to as spatio‐directional Gaussian mixture models (SDMMs). In particular, ... -
Path Guiding with Vertex Triplet Distributions
(The Eurographics Association and John Wiley & Sons Ltd., 2022)Good importance sampling strategies are decisive for the quality and robustness of photorealistic image synthesis with Monte Carlo integration. Path guiding approaches use transport paths sampled by an existing base sampler ... -
Path Integral Methods for Light Transport Simulation: Theory and Practice
(The Eurographics Association, 2014)We are witnessing a renewed research interest in robust and efficient light transport simulation based on statistical methods. This research effort is propelled by the desire to accurately render general environments with ... -
Path Integration for Light Transport in Volumes
(The Eurographics Association, 2003)Simulating the transport of light in volumes such as clouds or objects with subsurface scattering is computationally expensive. We describe an approximation to such transport using path integration. Unlike the more commonly ... -
Path Line Oriented Topology for Periodic 2D Time-Dependent Vector Fields
(The Eurographics Association, 2006)This paper presents an approach to extracting a path line oriented topological segmentation for periodic 2D timedependent vector fields. Topological methods aiming in capturing the asymptotic behavior of path lines rarely ... -
Path Planning for Crowds: From Shared Goals to Individual Behaviors
(The Eurographics Association, 2005)This paper presents a novel approach for path planning in the context of crowds animation. The solution produces several paths joining each user-defined pair of locations in the environment. Pairs are possible initial/goal ... -
Path Regeneration for Interactive Path Tracing
(The Eurographics Association, 2010)Rendering of photo-realistic images at interactive frame rates is currently an extensively researched area of computer graphics.Many of these approaches attempt to utilize the computational power of modern graphics hardware ... -
Path Sampling Techniques for Efficient Light Transport Simulation
(2015-06)Reproducing the interactions between light and matter in a physically accurate way can significantly improve the realistic appearance of synthetic images, however such effects can be very computationally expensive to ... -
Path Seeds and Flexible Isosurfaces Using Topology for Exploratory Visualization
(The Eurographics Association, 2003)Morse theory and the Reeb graph give topological summaries of the behaviour of continuous scalar functions. The contour tree augments the Reeb graph for the isosurfaces in a volume to store seed sets, which are starting ... -
Path Space Regularization for Holistic and Robust Light Transport
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We propose a simple yet powerful regularization framework for robust light transport simulation. It builds on top of existing unbiased methods and resorts to a consistent estimation using regularization only for paths which ... -
Path Tracing on Massively Parallel Neuromorphic Hardware
(The Eurographics Association, 2012)Ray tracing on parallel hardware has recently benefit from significant advances in the graphics hardware and associated software tools. Despite this, the SIMD nature of graphics card architectures is only able to perform ... -
Path Visualization for Adjacency Matrices
(The Eurographics Association, 2007)For displaying a dense graph, an adjacency matrix is superior than a node-link diagram because it is more compact and free of visual clutter. A node-link diagram, however, is far better for the task of path finding because ... -
Path-based Control of Smoke Simulations
(The Eurographics Association, 2006)In this paper, we propose a novel path-based control method for generating realistic smoke animations. Our method allows an animator to specify a 3D curve for the smoke to follow. Path control is then achieved using a ... -
Path-line Oriented Visualization of Dynamical Flow Fields
(2008)An effective visual representation of dynamical flow behavior is still a challenging problem of modern flow visualization. Path-lines are important characteristic curves of dynamical flow fields. In this thesis, we focus ... -
Path-space Motion Estimation and Decomposition for Robust Animation Filtering
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Renderings of animation sequences with physics-based Monte Carlo light transport simulations are exceedingly costly to generate frame-by-frame, yet much of this computation is highly redundant due to the strong coherence ...
