  • Visual Embedding: A Model for Visualization

    Publication Year: 2014 , Page(s): 10 - 15
    Cited by:  Papers (3)

    The authors propose visual embedding as a model for automatically generating and evaluating visualizations. A visual embedding is a function from data points to a space of visual primitives that measurably preserves structures in the data (domain) within the mapped perceptual space (range). The authors demonstrate its use with three examples: coloring of neural tracts, scatterplots with icons, and... View full abstract»

  • Investigating Landfill Contamination by Visualizing Geophysical Data

    Publication Year: 2014 , Page(s): 16 - 21

    Geophysical experts aimed to establish a method to identify contamination by landfill leakage without chemically analyzing subsoil samples, which is time-consuming and expensive. To that end, researchers developed a software package that let the experts create 3D visualizations of geophysical data acquired around the landfill and apply statistical analysis to detect anomalous values. The data used... View full abstract»

    Advances in computational methods and hardware platforms provide efficient processing of medical-imaging datasets for surgical planning. For neurosurgical interventions employing a straight access path, planning entails selecting a path from the scalp to the target area that's of minimal risk to the patient. A proposed GPU-accelerated method enables interactive quantitative estimation of the risk ... View full abstract»

    Estimating peoples' attention to regions of large public displays has been a problem since those displays' advent. Unlike with traditional interaction with a Web browser, you can't calculate a clickstream. A method for estimating where users are looking could partly overcome this issue. Researchers evaluated how several factors (head movement, individual users, the users' locations, and the amount... View full abstract»

    Contingency analysis employs different measures to model scenarios, analyze them, and then derive the best response to any threats. A proposed visual-analytics pipeline for power grid management can transform approximately 100 million contingency scenarios to a manageable size and form. Grid operators can examine individual scenarios and devise preventive or mitigation strategies in a timely manne... View full abstract»

  • Highly Parallel Algorithms for Visual-Perception-Guided Surface Remeshing

    Publication Year: 2014 , Page(s): 52 - 64

    A proposed framework for remeshing polygonal models employs mesh-free techniques for processing surface sample points. It's robust to input models with problematic connectivity, and the geometric processing of points runs easily in parallel on a GPU. The framework extracts visual-perception information in the image space and maps it back to the Euclidean space. On the basis of these visual cues, t... View full abstract»

  • Beautiful Math, Part 2: Aesthetic Patterns Based on Fractal Tilings

    Publication Year: 2014 , Page(s): 68 - 76
    Request Permissions | Click to expandAbstract | PDF file iconPDF (9801 KB) |  | HTML iconHTML  

    A fractal tiling (f-tiling) is a tiling whose boundary is fractal. This article presents two families of rare, infinitely many f-tilings. Each f-tiling is constructed by reducing tiles by a fixed scaling factor, using a single prototile, which is a segment of a regular polygon. The authors designed invariant mappings to automatically produce appealing seamless, colored patterns from such tilings. View full abstract»
