• Exploiting Human Actions and Object Context for Recognition Tasks 

      Moore, Darnell Janssen; Essa, Irfan A.; Hayes, M. H. (Monson H.) (Georgia Institute of Technology, 1999)
      Our goal is to exploit human motion and object context to perform action recognition and object classification. Towards this end, we introduce a framework for recognizing actions and objects by measuring image-, object- ...
    • Object Spaces: Context Management for Human Activity Recognition 

      Moore, Darnell Janssen; Essa, Irfan A.; Hayes, M. H. (Monson H.) (Georgia Institute of Technology, 1998)
      In this paper, we propose a vision-based method for developing computer awareness of human activities. We present an object-oriented approach called ObjectSpaces that encapsulates context into scene objects. Objects provide ...
    • Recognizing Workshop Activity Using Body Worn Microphones and Accelerometers 

      Atrash, Amin; Starner, Thad (Georgia Institute of Technology, 2003)
      Most gesture recognition systems analyze gestures intended for communication (e.g. sign language) or for command (e.g. navigation in a virtual world). We attempt instead to recognize gestures made in the course of performing ...
    • Robust Tracking of People by a Mobile Robotic Agent 

      Tanawongsuwan, Rawesak; Stoytchev, Alexander; Essa, Irfan A. (Georgia Institute of Technology, 1999)
      We present methods for tracking people in dynamic and changing environments from camera mounted on a mobile robot. We describe processes to extract color, motion, and depth information from video and we present methods to ...
    • 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 ...
