Visual Analysis of Confocal Raman Spectroscopy Data using Cascaded Transfer Function Design
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
2D Confocal Raman Microscopy (CRM) data consist of high dimensional per-pixel spectral data of 1000 bands and allows for complex spectral and spatial-spectral analysis tasks, i.e., in material discrimination, material ...
Minimum-Displacement Overlap Removal for Geo-referenced Data Visualization
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Given a set of rectangles embedded in the plane, we consider the problem of adjusting the layout to remove all overlap while preserving the orthogonal order of the rectangles. The objective is to minimize the displacement ...
Linear Discriminative Star Coordinates for Exploring Class and Cluster Separation of High Dimensional Data
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
One main task for domain experts in analysing their nD data is to detect and interpret class/cluster separations and outliers. In fact, an important question is, which features/dimensions separate classes best or allow a ...
Visual Exploration of Global Trade Networks with Time-Dependent and Weighted Hierarchical Edge Bundles on GPU
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
The UN Comtrade database is the world's largest repository of bilateral trade data. Their complexity poses a challenge to visualization systems, leading to issues such as scalability and visual clutter. Thus, we propose a ...
Concentric Spherical Representation for Omnidirectional Soft Shadow
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Soft shadows play an important role in photo‐realistic rendering. Although there are many efficient soft shadow algorithms, most of them focus on the one‐side light source situation, where a planar light source is on the ...
Practical Path Guiding for Efficient Light-transport Simulation
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
We present a robust, unbiased technique for intelligent light-path construction in path-tracing algorithms. Inspired by existing path-guiding algorithms, our method learns an approximate representation of the scene's ...
Photometric Stabilization for Fast-forward Videos
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Videos captured by consumer cameras often exhibit temporal variations in color and tone that are caused by camera autoadjustments like white-balance and exposure. When such videos are sub-sampled to play fast-forward, as ...
High-resolution 360 Video Foveated Stitching for Real-time VR
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
In virtual reality (VR) applications, the contents are usually generated by creating a 360 video panorama of a real-world scene. Although many capture devices are being released, getting high-resolution panoramas and ...
A Probabilistic Framework for Component-based Vector Graphics
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
We propose a framework for data-driven manipulation and synthesis of component-based vector graphics. Using labelled vector graphical images of a given type of object as input, our processing pipeline produces training ...
Albero: A Visual Analytics Approach for Probabilistic Weather Forecasting
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Probabilistic weather forecasts are amongst the most popular ways to quantify numerical forecast uncertainties. The analog regression method can quantify uncertainties and express them as probabilities. The method comprises ...
