AB Consumer sites such as MapQuest, Yahoo! Maps, and Google Maps compete to improve their interfaces and data relevance to better appeal to the browsing public. But innovation in online mapping isn't limited to these household names. Sites for the public good, such as those the US government manages, provide graphical access to data buried in such sources as the US Department of Agriculture Forest Service and the decennial census. Meanwhile, community mapping sites let the public provide local details, find nearby colleagues, and organize information in ways unknown 10 years ago.

AB A computer system for interactively creating marbling textures is built on the physical model of the traditional marbling process. The approach generates marbling designs as the result of color advection in the 2D flow fields obtained by numerically solving the Navier-Stokes equations on the GPU with a multigrid solver.

TI Rainbow Color Map (Still) Considered Harmful
A1 David Borland,

K1 rainbow color map
K1 color map
K1 visualization toolkits
AB Despite much published research on its deficiencies, the rainbow color map is prevalent in the visualization community. The authors present survey results showing that the rainbow color map continues to appear in more than half of the relevant papers in IEEE Visualization Conference proceedings. Its use is encouraged by its selection as the default color map used in most visualization toolkits that the authors inspected. The visualization community must do better. In this article, the authors reiterate the characteristics that make the rainbow color map a poor choice, provide examples that clearly illustrate these deficiencies even on simple data sets, and recommend better color maps for several categories of display.

AB Simulation-based training using VR techniques is a promising alternative to traditional training in minimally invasive surgery (MIS). Simulators let the trainee touch, feel, and manipulate virtual tissues and organs through the same surgical tool handles used in actual MIS while viewing images of tool-tissue interactions on a monitor as in real laparoscopic procedures.

AB Scientists of the Desert Research Institute's atmospheric, hydrological, and earth and ecosystem science divisions sift through vast amounts of data gathered from sophisticated instrumentation and computational models. To help address the data analysis needs that stem from the growing volume of data, DRI established the Center for Advanced Visualization, Computation, and Modeling (CAVCaM) to foster DRI's move into interactive, large-scale, 3D visualization of these and other environmental research issues. The authors' mission is two-pronged. First, they seek to partner with their researcher collaborators at DRI and the larger scientific communities through the development and use of better visualization tools. Second, they work with research sponsors to create visualization applications for training and simulation. To best achieve these goals, their underlying philosophy is to use established standards and generic tools (ideally open source) and contribute back to the opensource community.

Realizing that there is a huge foreseeable demand for mobile game developers, Motorola has formed a partnership with GamePipe Labs at the University of Southern California. The purpose of this partnership is to provide a platform to train the next generation of mobile game developers using design principles unique to mobile games. The authors describe the process, challenges, and results of this effort from both the technical and design aspects.

A1 Richard Szeliski,

K1 computational photography
AB Since their inception over three decades ago, the fields of computer vision, image processing, and computer graphics have been concerned with analyzing, manipulating, and synthesizing images using numerical algorithms. While these three fields continue to evolve in a loosely coupled manner, users' near-ubiquitous access to digital cameras and personal computers has spurred renewed interest in what is now dubbed computational photography, which lies at the intersection of these fields. The Guest Editors provide an overview of computational photography's evolution, provide links to additional resources, and introduce the articles they've selected for the issue.

AB Laplacian instability is the physical mechanism driving pattern formation in many disparate natural phenomena. Current algorithms for simulating this instability are slow and memory intensive. A new algorithm, based on the dielectric breakdown model from physics, is more than three orders of magnitude faster than previous methods and decreases memory use by two orders of magnitude.

AB This paper introduces a framework to design optical splitting tree to perform computational photography tasks that require many sensors with a common optical axis. As the number of sensors increases, designing a good optical system is often difficult because the components have nonideal characteristics. The authors describe an optimization tool takes this into account and finds "good" designs as specified by several weighted coefficients. Assisted by this optimizer, they demonstrate high-dynamic range, focusing, matting, high-speed, and hybrid imaging implemented on a single, reconfigurable camera containing eight sensors.

AB Defocus matting is a fully automatic and passive method for pulling mattes from video captured with coaxial cameras that have different depths of field and planes of focus. Nonparametric sampling can accelerate the video-matting process from minutes to seconds per frame. In addition, a super-resolution technique efficiently bridges the gap between mattes from high-resolution video cameras and those from low-resolution cameras. Off-center matting pulls mattes for an external high-resolution camera that doesn't share the same center of projection as the low-resolution cameras used to capture the defocus matting data.
