Improving Scans of Black and White photographs by Recovering the Print Maker's Artistic Intent
(The Eurographics Association, 2008)In this paper we propose a method that reverse engineers the aesthetic decisions made by a print maker to produce a print from a negative, namely cropping, contrast selection, and dodging-and-burning. It then re-applies ... -
Improving Shadow Map Filtering with Statistical Analysis
(The Eurographics Association, 2011)Shadow maps are widely used in real-time applications. Shadow maps cannot be filtered linearly as regular textures, thus undersampling leads to severe aliasing. This problem has been attacked by methods that transform the ... -
Improving SIMD Efficiency for Parallel Monte Carlo Light Transport on the GPU
(ACM, 2011)Monte Carlo Light Transport algorithms such as Path Tracing (PT), Bi-Directional Path Tracing (BDPT) and Metropolis Light Transport (MLT) make use of random walks to sample light transport paths. When parallelizing these ... -
Improving Spectral Upsampling with Fluorescence
(The Eurographics Association, 2020)Modern photorealistic rendering simulates spectral behaviour of light. Since many assets are still created in different RGB color spaces, spectral upsampling of the RGB colors to a spectral representation is required to ... -
Improving Stability and Compactness in Street Layout Visualizations
(The Eurographics Association, 2011)We present and evaluate improvements for Street Layout, a technique that can be used for visualizing evolving hierarchical data such as file structures or software systems. Street Layouts represent data as street networks, ... -
Improving text entry performance on tablet devices
(The Eurographics Association, 2020)In order to improve the text entry speed and error rate on tablet devices, we developed and tested 5 virtual keyboard variants. Some variants try to avoid errors by highlighting the next four most probable keys, either by ... -
Improving the digitization of shape and color of 3D artworks in a cluttered environment
(The Eurographics Association, 2013)We propose an approach for improving the digitization of shape and color of 3D artworks in a cluttered environment using 3D laser scanning and flash photography. In order to separate clutter from acquired material, ... -
Improving the Dwivedi Sampling Scheme
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Despite recent advances in Monte Carlo rendering techniques, dense, high-albedo participating media such as wax or skin still remain a difficult problem. In such media, random walks tend to become very long, but may still ... -
Improving the Experience of Scenes with a Large Field of View using Shift Lens Perspective
(The Eurographics Association, 2005)In interactive computer graphics such as games and interactive panoramic photos, users are often presented a view with a larger field of view than would correspond to the distance to and size of the screen on which the ... -
Improving the Parameterization of Approximate Subdivision Surfaces
(The Eurographics Association and Blackwell Publishing Ltd., 2012)We provide a method for improving the parameterization of patching schemes that approximate Catmull-Clark subdivision surfaces, such that the new parameterization conforms better to that of the original subdivision surface. ... -
Improving the Quality of Multi-resolution Volume Rendering
(The Eurographics Association, 2006)We propose a novel method to improve the quality of multi-resolution visualizations. We reduce aliasing artifacts by approximating the data distribution with a Gaussian basis function at each level of detail for more ... -
Improving the Scalability of Interactive Visualization Systems for Exploring Threaded Conversations
(The Eurographics Association, 2019)Large threaded conversations, such as those found on YCombinator's HackerNews, are typically presented in a way that shows individual comments clearly, but can obscure larger trends or patterns within the conversational ... -
Improving the Sensitivity of Statistical Testing for Clusterability with Mirrored-Density Plots
(The Eurographics Association, 2020)For many applications, it is crucial to decide if a dataset possesses cluster structures. This property is called clusterability and is usually investigated with the usage of statistical testing. Here, it is proposed to ... -
Improving Topological Segmentation of Three-dimensional Vector Fields
(The Eurographics Association, 2003)We present three enhancements to accelerate the extraction of separatrices of three-dimensional vector fields, using intelligently selected "sample" streamlines. These enhancements reduce the number of needed sample ... -
Improving View Independent Rendering for Multiview Effects
(The Eurographics Association, 2022)This paper describes improvements to view independent rendering (VIR) that make it much more useful for multiview effects. Improved VIR's (iVIR's) soft shadows are nearly identical in quality to VIR's and produced with ... -
The Impulse Graph: A New Dynamic Structure For Global Collisions
(Blackwell Publishers Ltd and the Eurographics Association, 2000)In interactive virtual environments and dynamic simulations, collisions between complex objects and articulated bodies may occur simultaneously at multiple points or regions of interference. Many solutions to the collision ... -
The Impulse Particle-In-Cell Method
(The Eurographics Association and John Wiley & Sons Ltd., 2024)An ongoing challenge in fluid animation is the faithful preservation of vortical details, which impacts the visual depiction of flows. We propose the Impulse Particle-In-Cell (IPIC) method, a novel extension of the popular ... -
Impulse Responses for Precomputing Light from Volumetric Media
(The Eurographics Association, 2019)Modern interactive rendering can rely heavily on precomputed static lighting on surfaces and in volumes. Scattering from volumetric media can be similarly treated using precomputation, but transport from volumes onto ... -
In at the Deep End: An Activity-Led Introduction to Creative Computing with Interactive Computer Graphics
(The Eurographics Association, 2011)Misconceptions about the nature of the computing discipline(s) pose a serious problem to faculties that offer computing degrees, as students enrolling on their programmes come to realise that their expectations are not met ... -
In at the Deep End: An Activity-Led Introduction to First Year Creative Computing
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Misconceptions about the nature of the computing disciplines pose a serious problem to university faculties that offer computing degrees, as students enrolling on their programmes may come to realise that their expectations ...
