Active Contours Using a Constraint-Based Implicit Representation
Found in: Computer Vision and Pattern Recognition, IEEE Computer Society Conference on
By Bryan S. Morse, Weiming Liu, Terry S. Yoo, Kalpathi Subramanian
Issue Date:June 2005
pp. 285-292
<p>We present a new constraint-based implicit active contour, which shares desirable properties of both parametric and implicit active contours. Like parametric approaches, their representation is compact and can be manipulated interactively. Like ot...
 
Interpolating Implicit Surfaces from Scattered Surface Data Using Compactly Supported Radial Basis Functions
Found in: Shape Modeling and Applications, International Conference on
By Bryan S. Morse, Terry S. Yoo, David T. Chen, Penny Rheingans, K.R. Subramanian
Issue Date:May 2001
pp. 0089
We describe algebraic methods for creating implicit surfaces using linear combinations of radial basis interpolants to form complex models from scattered surface points. Shapes with arbitrary topology are easily represented without the usual interpolation ...
 
Direct Visualization of Volume Data
Found in: IEEE Computer Graphics and Applications
By Terry S. Yoo, Ulrich Neumann, Henry Fuchs, Stephen M. Pizer, Tim Cullip, John Rhoades, Ross Whitaker
Issue Date:July 1992
pp. 63-71
<p>A combination of segmentation tools and fast volume renderers that provides an interactive exploration environment for volume visualization is discussed. The tools and renderers include mechanisms that distribute volume data across multiple proces...
 
Exploring Surface Characteristics with Interactive Gaussian Images (A Case Study)
Found in: Visualization Conference, IEEE
By Bradley Lowekamp, Penny Rheingans, Terry S. Yoo
Issue Date:November 2002
pp. N/A
The Gauss map projects surface normals to a unit sphere, providing a powerful visualization of the geometry of a graphical object. It can be used to predict visual events caused by changes in lighting, shading, and camera control. We present an interactive...
 
Visualization Research Challenges: A Report Summary
Found in: Computing in Science and Engineering
By Robert Moorhead, Chris Johnson, Tamara Munzner, Hanspeter Pfister, Penny Rheingans, Terry S. Yoo
Issue Date:July 2006
pp. 66-73
In 2004, the NSF and the US National Institutes of Health convened the Visualization Research Challenges Executive Committee to report on visualization's potential as a technology. The reports' authors summarize their findings and present examples of usefu...
 
NIH-NSF Visualization Research Challenges Report Summary
Found in: IEEE Computer Graphics and Applications
By Tamara Munzner, Chris Johnson, Robert Moorhead, Hanspeter Pfister, Penny Rheingans, Terry S. Yoo
Issue Date:March 2006
pp. 20-24
Nearly twenty years ago, the US National Science Foundation (NSF) convened a panel to report on the potential of visualization as a new technology, jump-starting funding for computer-based visualization. Last year, the NSF and US National Institutes of Hea...
 
Digital Design of a Surgical Simulator for Interventional Magnetic Resonance Imaging
Found in: Visualization Conference, IEEE
By Terry S. Yoo, Penny Rheingans
Issue Date:October 1999
pp. 6
We present the design of a simulator for a prototype interventional magnetic resonance imaging scanner. This MRI scanner is integrated with an operating theater, enabling new techniques in minimally invasive surgery. The simulator is designed with a threef...

Issue Date:July 2005
pp. 252-es
We present a new constraint-based implicit active contour, which shares desirable properties of both parametric and implicit active contours. Like parametric approaches, their representation is compact and can be manipulated interactively. Like other impli...

Anatomic modeling from unstructured samples using variational implicit surfaces
Found in: ACM SIGGRAPH 2005 Courses (SIGGRAPH '05)
By Bryan Morse, K. R. Subramanian, Michael J. Ackerman, Penny Rheingans, Terry S. Yoo
Issue Date:July 2005
pp. 245-es
We describe the use of variational implicit surfaces (level sets of an embedded generating function modeled using radial basis interpolants) in anatomic modeling. This technique allows the practitioner to employ sparsely and unevenly sampled data to repres...
     
Medical applications of implicit surfaces
Found in: ACM SIGGRAPH 2005 Courses (SIGGRAPH '05)
By Terry S. Yoo
Issue Date:July 2005
pp. 223-es
We analyze a moving least squares algorithm for reconstructing a surface from point cloud data. Our algorithm defines an implicit function I whose zero set U is the reconstructed surface. We prove that I is a good approximation to the signed distance funct...
     
Compactly supported RBFs in the management of implicit surfaces
Found in: ACM SIGGRAPH 2005 Courses (SIGGRAPH '05)
By Terry S. Yoo
Issue Date:July 2005
pp. 58-es
We investigate the CW-complex as a data structure for visualizing and controlling the topology of implicit surfaces. Previous methods for contolling the blending of implicit surfaces redefined the contribution of a metaball or unioned blended components. M...
     
Modern techniques for implicit modeling
Found in: ACM SIGGRAPH 2005 Courses (SIGGRAPH '05)
By James F. O'Brien, Terry S. Yoo
Issue Date:July 2005
pp. 1-es
The SIGGRAPH conference is an exciting event, but it is often an intimidating experience for first-time attendees. There are so many new terms, new concepts, and new products to try to understand. It is like standing in a room with 100 doors and having no ...
     
Open source software for medical image processing and visualization
Found in: Communications of the ACM
By Michael J. Ackerman, Terry S. Yoo
Issue Date:February 2005
pp. 55-59
Societies often create smaller subsets or communities that connect with one another for commerce and intellectual exchange over mutual interests. In science and engineering, the need for communication among researchers is often hampered by artificial barri...
