      Herrtwich, R. G. (Ralf Guido); Foley, James D.; Encarnacao, Jose Luis (Georgia Institute of Technology, 1995)
      In July 1994, leading international multimedia researchers met in the International Computer Science Research Center at Dagstuhl Castle to discuss the fundamentals and perspectives of their field. The purpose of the seminar ...
    • PhotoMeter: Easy-to-use MonoGraphoMetrics 

      Muller, Hendrik; Rossignac, Jaroslaw R. (Georgia Institute of Technology, 2004)
      MonoGraphoMetrics is the science of computing 3D measures from a single image. Several recent research activities have produced theoretical principles and practical tools for extracting 3D measures from uncalibrated ...
    • Physically Accurate Synthetic Images for Computer Vision System Design 

      Rushmeier, Holly E.; Parker, Johne' Michelle; Lee, Kok-Meng (Georgia Institute of Technology, 1991)
      The design of a computer vision system for part presentation is a complex hardware/software problem. In the past, standard renderings of parts available from CAD systems have been used as aids in the design process. However, ...
    • Physically Realistic Morphing 

      Hodgins, Jessica K.; Pollard, Nancy S. (Georgia Institute of Technology, 1997)
      This paper describes an algorithm for automatically adapting existing animated behaviors to new actors with different physical characteristics. When simulation is used for animation, this is a difficult problem because a ...
    • Planning of joint trajectories for humanoid robots using B-spline wavelets 

      Ude, Ales; Atkeson, Christopher G.; Riley, Marcia (Georgia Institute of Technology, 2000)
      The formulation and optimization of joint trajectories for humanoid robots is quite different form this same task for standard robots because of the complexity of the humanoid robots' kinematics. In this paper we exploit ...
    • Playing Detective: Using AI for Sensemaking in Investigative Analysis 

      Goel, Ashok K.; Adams, Summer; Cutshaw, Neil; Sugandh, Neha (Georgia Institute of Technology, 2009)
      The sensemaking task in investigative analysis generates models that connect entities and events in an input stream of data. We describe two knowledge systems for aiding sensemaking in investigative analysis. The Spade ...
    • PML: Representing Procedural Domains for Multimedia Presentations 

      Ram, Ashwin; Catrambone, Richard; Guzdial, Mark; Kehoe, Colleen Mary; McCrickard, D. Scott; Stasko, John T. (Georgia Institute of Technology, 1998)
      A central issue in the development of multimedia systems is the presentation of the information to the user of the system and how to best represent that information to the designer of the system. Typically, the designers ...
