    • An Extensible Interactor Toolkit for Enhancing Information Awareness 

      McCrickard, D. Scott (Georgia Institute of Technology, 1998)
      The typical computer application follows a set pattern: it is executed by a user, it provides responses to commands issued by the user, and it is terminated by the user when it is no longer needed. However, the advent of ...
    • Extraction of Topologically Simple Isosurfaces from Volume Datasets 

      Szymczak, Andrzej; Vanderhyde, James (Georgia Institute of Technology, 2003)
      There are numerous algorithms in graphics and visualization whose performance is known to decay as the topological complexity of the input increases. On the other hand, the standard pipeline for 3D geometry acquisition ...

      Somani, Ramswaroop; Rossignac, Jaroslaw R. (Georgia Institute of Technology, 2003)
      The FanGrower algorithm proposed here segments a manifold triangle mesh into regions (called caps), which may each be closely approximated by a triangle-fan. Once the caps are formed, their rims, which form the inter-cap ...
    • Fast and Memory Efficient Polygonal Simplification 

      Lindstrom, Peter; Turk, Greg (Georgia Institute of Technology, 1998)
      Conventional wisdom says that in order to produce high-quality simplified polygonal models, one must retain and use information about the original model during the simplification process. We demonstrate that excellent ...
    • Fast Asymmetric Learning for Cascade Face Detection 

      Wu, Jianxin; Brubaker, S. Charles; Mullin, Matthew D.; Rehg, James M. (Georgia Institute of Technology, 2005)
      A cascade face detector uses a sequence of node classifiers to distinguish faces from non-faces. This paper presents a new approach to design node classifiers in the cascade detector. Previous methods used machine learning ...
    • Feature-Based Surface Parameterization and Texture Mapping 

      Zhang, Eugene; Mischaikow, Konstantin Michael; Turk, Greg (Georgia Institute of Technology, 2003)
      Surface parameterization is necessary for many graphics tasks: texture-preserving simplification, remeshing, surface painting, and pre-computation of solid textures. The stretch caused by a given parameterization determines ...

    • Finding Lost Objects: Informing the Design of Ubiquitous Computing Services for the Home 

      Peters, Rodney E.; Pak, Richard; Abowd, Gregory D.; Fisk, Arthur D.; Rogers, Wendy A. (Georgia Institute of Technology, 2004)
      Factors that influence the finding of objects can be numerous and complex. Ubiquitous computing solutions for this problem begin with underlying technologies (location-sensing and capture) as building blocks for real ...
    • Finger Sculpting with Digital Clay 

      Gargus, Joshua; Kim, Byungmoon; Rossignac, Jaroslaw R.; Shaw, Christopher D. (Georgia Institute of Technology, 2002)
      "Digital Clay" is a term that signifies a computer-controlled physical surface, capable of taking any of a wide variety of possible shapes in response to changes in a digital 3D model or changes in the pressure exerted ...
    • Finger Sculpting with Digital Clay: 3D Shape Input and Output through a Computer-Controlled Real Surface
