Progressive Visibility Caching for Fast Indirect Illumination
(The Eurographics Association, 2013)
Rendering realistic images requires exploring the vast space of all possible paths that light can take between emitters and receivers. Thanks to the advances in rendering we can tackle this problem using different algorithms; ...
Transfusive Weights for Content-Aware Image Manipulation
(The Eurographics Association, 2013)
Many image editing operations, such as colorization, matting or deformation, can be performed by propagating user-defined sparse constraints (e.g. scribbles) to the rest of the image using content-aware weight functions. ...
A Tracking Approach for the Skeletonization of Tubular Parts of 3D Shapes
(The Eurographics Association, 2013)
In this paper we propose a new simple and efficient method to characterize shapes by segmenting their elongated parts and characterizing them with their centerlines. We call it Tubular Section Tracking, because it consists ...
Dynamic Time Warping Based 3D Contours
(The Eurographics Association, 2013)
In this work, we present a method for computing 3D contours from the silhouettes of objects in multiple views. Our approach unwraps contours into 1D signals and computes an efficient, globally optimal alignment using a ...
Interactive Direct Volume Rendering with Many-light Methods and Transmittance Caching
(The Eurographics Association, 2013)
In this paper we present an interactive global illumination method for Direct Volume Rendering (DVR) based on the many-light approach, a class of global illumination methods which gained much interest recently. We extend ...
Closed-Form Hierarchical Finite Element Models for Part-Based Object Detection
(The Eurographics Association, 2013)
In this work we address part-based object detection under variability of part shapes and spatial relations. Our approach bases on the hierarchical finite element modeling concept of Engel and Tönnies [ET09a, ET09b]. They ...
Level of Detail for Real-Time Volumetric Terrain Rendering
(The Eurographics Association, 2013)
Terrain rendering is an important component of many GIS applications and simulators. Most methods rely on heightmap-based terrain which is simple to acquire and handle, but has limited capabilities for modeling features ...
Visualization and Analysis of Lumbar Spine Canal Variability in Cohort Study Data
(The Eurographics Association, 2013)
Large-scale longitudinal epidemiological studies, such as the Study of Health in Pomerania (SHIP), investigate thousands of individuals with common characteristics or experiences (a cohort) including a multitude of ...
Optimising Aperture Shapes for Depth Estimation
(The Eurographics Association, 2013)
The finite depth of field of a real camera can be used to estimate the depth structure of a scene. While the distance of an object from the plane in focus determines the defocus blur size, the shape of the aperture determines ...
Geometric Point Light Source Calibration
(The Eurographics Association, 2013)
We present a light position calibration technique based on a general arrangement of at least two reflective spheres in a single image. Contrary to other techniques we do not directly intersect rays for triangulation but ...
