    • Automated Assessment of Surgical Skills Using Frequency Analysis 

      Zia, Aneeq; Sharma, Yachna; Bettadapura, Vinay; Sarin, Eric L.; Clements, Mark A.; Essa, Irfan (Georgia Institute of Technology, 2015)
      We present an automated framework for visual assessment of the expertise level of surgeons using the OSATS (Objective Structured Assessment of Technical Skills) criteria. Video analysis techniques for extracting motion ...
    • The Bayes Tree: An Algorithmic Foundation for Probabilistic Robot Mapping 

      Kaess, Michael; Ila, Viorela; Roberts, Richard; Dellaert, Frank (Georgia Institute of TechnologySpringer Berlin / Heidelberg, 2010-12)
      We present a novel data structure, the Bayes tree, that provides an algorithmic foundation enabling a better understanding of existing graphical model inference algorithms and their connection to sparse matrix factorization ...
    • Categorizing Turn-Taking Interactions 

      Prabhakar, Karthir; Rehg, James M. (Georgia Institute of TechnologySpringer-Verlag Berlin / Heidelberg, 2012-10)
      We address the problem of categorizing turn-taking interactions between individuals. Social interactions are characterized by turn-taking and arise frequently in real-world videos. Our approach is based on the use of ...
    • Humanoid HRP2-DHRC for Autonomous and Interactive Behavior 

      Kagami, Satoshi; Nishiwaki, K.; Kuffner, James; Thompson, S.; Chestnutt, J.; Stilman, Mike; Michel, P. (Georgia Institute of TechnologySpringer Berlin / Heidelberg, 2007)
      Recently, research on humanoid-type robots has become increasingly active, and a broad array of fundamental issues are under investigation. However, in order to achieve a humanoid robot which can operate in human environments, ...
    • Identifying regional dialects in online social media 

      Eisenstein, Jacob (Georgia Institute of Technology, 2014-08-06)
      Electronic social media offers new opportunities for informal communication in written language, while at the same time, providing new datasets that allow researchers to document dialect variation from records of natural ...
    • Joint Semantic Segmentation and 3D Reconstruction from Monocular Video 

      Kundu, Abhijit; Li, Yin; Dellaert, Frank; Li, Fuxin; Rehg, James M. (Georgia Institute of TechnologySpringer International, 2014-09)
      We present an approach for joint inference of 3D scene structure and semantic labeling for monocular video. Starting with monocular image stream, our framework produces a 3D volumetric semantic + occupancy map, which is ...
    • MCMC-based Multiview Reconstruction of Piecewise Smooth Subdivision Curves with a Variable Number of Control Points 

      Kaess, Michael; Zboinski, Rafal; Dellaert, Frank (Georgia Institute of TechnologySpringer Berlin / Heidelberg, 2004-05)
      We investigate the automated reconstruction of piecewise smooth 3D curves, using subdivision curves as a simple but flexible curve representation. This representation allows tagging corners to model nonsmooth features ...
    • An MCMC-based Particle Filter for Tracking Multiple Interacting Targets 

      Khan, Zia; Balch, Tucker; Dellaert, Frank (Georgia Institute of TechnologySpringer Berlin / Heidelberg, 2004-05)
      We describe a Markov chain Monte Carlo based particle filter that effectively deals with interacting targets, i.e., targets that are influenced by the proximity and/or behavior of other targets. Such interactions cause ...
    • Movement Pattern Histogram for Action Recognition and Retrieval 

      Ciptadi, Arridhana; Goodwin, Matthew S.; Rehg, James M. (Georgia Institute of TechnologySpringer International, 2014)
      We present a novel action representation based on encoding the global temporal movement of an action. We represent an action as a set of movement pattern histograms that encode the global temporal dynamics of an action. ...
    • My roomba is rambo: Intimate home appliances 

      Sung, Ja-Young; Guo, Lan; Grinter, Rebecca E.; Christensen, Henrik (Georgia Institute of TechnologySpringer Verlag, 2007-09)
      Robots have entered our domestic lives, but yet, little is known about their impact on the home. This paper takes steps towards addressing this omission, by reporting results from an empirical study of iRobot’s Roomba™, a ...
    • A Rao-Blackwellized Parts-Constellation Tracker 

      Schindler, Grant; Dellaert, Frank (Georgia Institute of TechnologySpringer Berlin / Heidelberg, 2005)
      We present a method for efficiently tracking objects represented as constellations of parts by integrating out the shape of the model. Parts-based models have been successfully applied to object recognition and tracking. ...
    • Sensing and estimation 

      Christensen, Henrik; Hager, G. (Georgia Institute of TechnologySpringer Verlag, 2008-05)
    • Weakly Supervised Learning of Object Segmentations from Web-Scale Video 

      Hartmann, Glenn; Grundmann, Matthias; Hoffman, Judy; Tsai, David; Kwatra, Vivek; Madani, Omid; Vijayanarasimhan, Sudheendra; Essa, Irfan A.; Rehg, James M.; Sukthankar, Rahul (Georgia Institute of TechnologySpringer-Verlag Berlin / Heidelberg, 2012-10)
      We propose to learn pixel-level segmentations of objects from weakly labeled (tagged) internet videos. Specifically, given a large collection of raw YouTube content, along with potentially noisy tags, our goal is to ...
