    Humans use intuition and experience to classify everything they perceive, but only if the distinguishing patterns are visible. Machine-learning algorithms can learn class information from data sets, but the created classes' meaning isn't always clear. A proposed mixed-initiative approach combines intuitive visualizations with machine learning to tap into the strengths of human and machine classifi... View full abstract»

    This special issue presents four articles demonstrating a first step from traditional interactive visualization to knowledge-assisted visualization. Knowledge-assisted visualization's objectives include sharing domain knowledge among different users and reducing the burden on users to acquire knowledge about complex visualization techniques. The four articles address this new challenge from differ... View full abstract»

    Computer-aided disease detection software effectively helps medical professionals use PA (posterior-anterior) and lateral (side) x-ray images to detect diseases such as lung cancer at early stages, which can be quite difficult. Typically, such software focuses only on PA x-ray images and uses image-processing and soft-computation techniques to identify potentially diseased areas. There's been litt... View full abstract»

    A 3D visualization environment contains domain information about geologic features in seismic data and lets users interactively steer segmentations on the basis of visual sources of information and knowledge. A user study demonstrates this approach's ability to transfer domain knowledge to nonexperts. View full abstract»

    Over the past decades, scientific visualization has helped tremendously to easily generate meaningful representations of complicated data sets. However, with data correlated over many dimensions and millions of points, only few of the standard techniques are directly applicable. Unsteady multifield visualizations require effective reduction of the data to be displayed. From a huge amount of inform... View full abstract»

    Developers who create applications for knowledge representation must contend with challenges in both the abundance of data and the variety of toolkits, architectures, and standards for representing it. Prajna is a flexible Java toolkit designed to overcome these challenges with an extensible architecture that supports both visualization and automated reasoning. View full abstract»

  • Application-Driven Compression for Visualizing Large-Scale Time-Varying Data

    We advocate an application-driven approach to compressing and rendering large-scale time-varying scientific-simulation data. Scientists often have specific visualization tasks in mind based on certain domain knowledge. For example, in the context of time-varying, multivariate volume-data visualization, a scientist's domain knowledge might include the salient isosurface of interest for some variabl...

  • Volumetric Ambient Occlusion for Real-Time Rendering and Games

    This new algorithm, based on GPUs, can compute ambient occlusion to inexpensively approximate global-illumination effects in real-time systems and games. The first step in deriving this algorithm is to examine how ambient occlusion relates to the physically founded rendering equation. The correspondence stems from a fuzzy membership function that defines what constitutes nearby occlusions. The nex... View full abstract»

    Despite the pursuit for increased realism in VR training simulations and massively multiplayer online games, we find little deployed capability to modify terrain. Usually, terrain is stored in a static database and then preprocessed to support multiple levels of detail and to rectify features with the ground. Also, dynamic-terrain research has concentrated on graphics simulations for single users;... View full abstract»

    Our seas and oceans hide a plethora of archaeological sites such as ancient shipwrecks that, overtime, are being destroyed through activities such as deepwater trawling and treasure hunting. In 2006, a multidisciplinary team of 11 European institutions established the Venus (Virtual Exploration of Underwater Sites) consortium to make underwater sites more accessible by generating thorough, exhaust...

    Can playing a video game help save lives? It might seem unlikely, especially if the first image that comes to mind at the word "gamer" is that of an overstimulated, underdeveloped teenager who desperately needs a suntan and a girlfriend. However, like many of today's gamers, video games are moving out of their parents' basement and into the real world. Video games are maturing and facing adaptatio... View full abstract»
