Route Visualization Using Detail Lenses
Found in: IEEE Transactions on Visualization and Computer Graphics
By Pushpak Karnick, David Cline, Stefan Jeschke, Anshuman Razdan, Peter Wonka
Publication Date: June 2009
pp. 235-247
We present a method designed to address some limitations of typical route map displays of driving directions. The main goal of our system is to generate a printable version of a route map that shows the overview and detail views of the route within a singl...
 
3D VQI: 3D Visual Query Interface
Found in: Information Technology: New Generations, Third International Conference on
By Subhash Uppalapati, John C. Femiani, Anshuman Razdan, Kevin Gary
Issue Date:April 2009
pp. 1347-1354
The 3D Visual Query Interface (3D VQI) is a web-based database application that allows for shape-based searches in addition to more traditional text-based queries of the 3D vessel dataset. This interface allows researchers remote access to vessel collectio...
 
Generating 3D Building Models from Architectural Drawings: A Survey
Found in: IEEE Computer Graphics and Applications
By Xuetao Yin, Peter Wonka, Anshuman Razdan
Issue Date:January 2009
pp. 20-30
Automatically generating 3D building models from 2D architectural drawings has many useful applications in the architecture engineering and construction community. This survey of model generation from paper and CAD-based architectural drawings covers the c...
 
Compressed Facade Displacement Maps
Found in: IEEE Transactions on Visualization and Computer Graphics
By Saif Ali, Jieping Ye, Anshuman Razdan, Peter Wonka
Issue Date:March 2009
pp. 262-273
We describe an approach to render massive urban models. To prevent a memory transfer bottleneck we propose to render the models from a compressed representation directly. Our solution is based on rendering crude building outlines as polygons and generating...
 
Thin Structure Segmentation and Visualization in Three-Dimensional Biomedical Images: A Shape-Based Approach
Found in: IEEE Transactions on Visualization and Computer Graphics
By Adam Huang, Gregory M. Nielson, Anshuman Razdan, Gerald E. Farin, D. Page Baluch, David G. Capco
Issue Date:January 2006
pp. 93-102
<p><b>Abstract</b>—This paper presents a shape-based approach in extracting thin structures, such as lines and sheets, from three-dimensional (3D) biomedical images. Of particular interest is the capability to recover cellular structures,...
 
Improved Geometric Constraints on Deformable Surface Model for Volumetric Segmentation
Found in: Geometric Modeling and Processing
By Jiuxiang Hu, Anshuman Razdan, Gregory M. Nielson, Gerald E. Farin
Issue Date:April 2004
pp. 237
In this paper, we present a deformable surface geometric model for segmenting targets from volumetric data. This model deforms under external forces only, and changes its geometry and topology by using improved geometric constraints. External forces are ca...
 
Volumetric Segmentation Using Weibull E-SD Fields
Found in: IEEE Transactions on Visualization and Computer Graphics
By Jiuxiang Hu, Anshuman Razdan, Gregory M. Nielson, Gerald E. Farin, D. Page Baluch, David G. Capco
Issue Date:July 2003
pp. 320-328
<p><b>Abstract</b>—This paper presents a coarse-grain approach for segmentation of objects with gray levels appearing in volume data. The input data is on a 3D structured grid of vertices <tmath>$v(i,j,k) $</tmath>, each assoc...
 
Acquisition, Representation, Query and Analysis of Spatial Data: A Demonstration 3D Digital Library
Found in: Digital Libraries, Joint Conference on
By Jeremy Rowe, Anshuman Razdan, Arleyn Simon
Issue Date:May 2003
pp. 147
The increasing power of techniques to model complex geometry and extract meaning from 3D information create complex data that must be described, stored, and displayed to be useful to researchers. Responding to the limitations of two-dimensional (2D) data r...
 
Digital library system: capture, analysis, query, and display 3D data
Found in: Proceedings of the second ACM/IEEE-CS joint conference on Digital libraries (JCDL '02)
By Anshuman Razdan, Jeremy Rowe
Issue Date:July 2002
pp. 382-382
This paper describes development of a storage, archival, and sketch-based query and retrieval system for 3D objects. The initial focus has been Native American ceramic vessels, scanned and defined as a set of three-dimensional triangulated meshes composed ...
