      Rossignac, Jaroslaw R.; Requicha, Aristides A. G. (Georgia Institute of Technology, 1999)
      A solid model is a digital representation of the geometry of an existing or envisioned physical object. Solid models are used in many industries, from entertainment to health care. They play a major role in the discrete-part ...
    • Solution Based Problem Evolution and Problem Inception in Biologically Inspired Design 

      Helms, Michael E. (Georgia Institute of Technology, 2011-08-08)
      Biologically inspired design is one of the most important movements in contemporary engineering design. The paradigm entails the use of biological systems as sources of ideas for the design of technological products. Thus, ...
    • Solving Computer Animation Problems with Numeric Optimization 

      Zordan, Victor B. (Georgia Institute of Technology, 2002)
      Optimization techniques have been used in computer animation to search for system parameters and control inputs in a variety of animated objects and characters. Researchers rely on numeric optimization to solve problems ...
    • Sonopticon: Auditory Display in Automobile Interface Design 

      Bayes, Joe; Pair, Jarrell; Shrum, Ed; Tolva, John (Georgia Institute of Technology, 1998)
      The multiplicity of interface elements in an automobile can present a hinderance to usability and safety. We prototyped and conducted preliminary testing of an automobile driving interface. Our key design principle was to ...
    • Sound Source Localization in Domestic Environment 

      Bian, Xuehai; Rehg, James Matthew; Abowd, Gregory D. (Georgia Institute of Technology, 2004)
      Sound source localization strategies can be traced back to radar and sonar localization systems. In the report, we will review the main challenges of sound source, especially talker, localization problem and current major ...
    • Space-Time Surface Simplification and Edgebreaker Compression for 2D Cel Animations 

      Kwatra, Vivek; Rossignac, Jaroslaw R. (Georgia Institute of Technology, 2002)
      Digitized cel animations are typically composed of frames containing a small number of regions; each region contains pixels of the same color and exhibits a significant level of shape coherence through time. To exploit ...
    • Spectral Predictors 

      Lindstrom, Peter; Rossignac, Jaroslaw R.; Ibarria, Lorenzo (Lawrence) (Georgia Institute of Technology, 2006)
      Many applications produce large high-precision scalar fields sampled on a regular grid. Lossless compression of such data is commonly done using predictive coding, in which weighted combinations of previously coded samples ...
    • Speech and Gesture Multimodal Control of a Whole Earth 3D Visualization Environment 

      Krum, David Michael; Omoteso, Olugbenga; Ribarsky, William; Starner, Thad; Hodges, Larry F. (Georgia Institute of Technology, 2002)
      A growing body of research shows several advantages to multimodal interfaces including increased expressiveness, exibility, and user freedom. This paper investigates the design of such an interface that integrates speech ...
    • Square Root SAM: Simultaneous Localization and Mapping via Square Root Information Smoothing 

      Dellaert, Frank (Georgia Institute of Technology, 2005)
      Solving the SLAM problem is one way to enable a robot to explore, map, and navigate in a previously unknown environment. We investigate smoothing approaches as a viable alternative to extended Kalman filter-based solutions ...
