    • On Handwriting Recognition System Performance: Some Experimental Results 

      Santos, Paulo J.; Baltzer, Amy J.; Badre, Albert; Henneman, Richard L.; Miller, Michael S. (Georgia Institute of Technology, 1992)
      Performance of a rule-based handwriting recognition system is considered. Performance limits of such systems are defined by the robustness of the character templates and the ability of the system to segment characters. ...
    • On the Design of Cascades of Boosted Ensembles for Face Detection 

      Brubaker, S. Charles; Wu, Jianxin; Sun, Jie; Mullin, Matthew D.; Rehg, James M. (Georgia Institute of Technology, 2005)
      Cascades of boosted ensembles have become popular in the object detection community following their highly successful introduction in the face detector of Viola and Jones. Since then, researchers have sought to improve ...
    • One Step Towards Multimedia Help: Adding Context-Sensitive Animated Help as One Ingredient 

      Sukaviriya, Piyawadee (Noi) (Georgia Institute of Technology, 1991)
      Users often have difficulties relating general help information to the specific computer tasks which they are attempting to complete. A factor contributing to this problem is the distance between the space in which help ...
    • Opportunistic Annexing for Handheld Devices: Opportunities and Challenges 

      Pierce, Jeffrey S.; Mahaney, Heather Elizabeth; Abowd, Gregory D. (Georgia Institute of Technology, 2003)
      Mobile devices such as PDAs and cellphones suffer from limited input and output capabilities. Unlike the processing and storage capabilities of these devices, which will improve over time, their input and output capabilities ...
    • Optimal Bit Allocation in 3D Compression 

      King, Davis; Rossignac, Jaroslaw R. (Georgia Institute of Technology, 1999)
      To use 3D models on the Internet or in other bandwidth-limited applications, it is often necessary to compress their triangle mesh representations. We consider the problem of balancing two forms of lossy mesh compression: ...
    • Optimized Blist Form (OBF) 

      Rossignac, Jaroslaw R. (Georgia Institute of Technology, 2007-05-23)
      Any Boolean expressions may be converted into positive-form, which has only union and intersection operators. Let E be a positive-form expression with n literals. Assume that the truth-values of the literals are read one ...
    • Organization and Simplification of High-Resolution 3D City Facades 

      Parry, Robert Mitchell; Ribarsky, William; Shaw, Christopher D.; Jang, Justin; Faust, Nick L. (Nickolas Lea) (Georgia Institute of Technology, 2002)
      This paper describes an approach for the organization and simplification of high-resolution geometry and imagery data for 3D buildings for interactive city navigation. At the highest level of organization, building data ...
    • Organizational Hierarchies for Real-Time, 4D Visualizations 

      Haus, Jacques; Newton, Gregory P.; Ribarsky, William; Faust, Nick L. (Nickolas Lea); Hodges, Larry F.; Newton, Gregory P. (Georgia Institute of Technology, 1996)
      This paper describes a 4D object hierarchy that is appropriate for the immense amount of time-dependent, 3D data associated with large scale simulations or information spaces. An organizational hierarchy approach is developed ...
    • OrthoMap: Homeomorphism-guaranteeing normal-projection map between surfaces 

      Chazal, Frederic; Lieutier, Andre; Rossignac, Jaroslaw R. (Georgia Institute of Technology, 2004)
      Consider two (n—1)-dimensional manifolds, S and Sʹ in Rn. We say that they are projection-homeomorphic when the closest projection of each one onto the other is a homeomorphism. We give tight conditions under which S and ...
