Current research projects



Past research projects:
                     Human Computer Interaction based on XVision
(left) interactive "pong" game, where the user plays with his hands (right) gesture recognition

(see example MPEG movie for the gesture recognition- it starts with a teaching step, where the system requests specific gestures followed by the recognition step showing the currently grabbed image in the upper small window and the matched template in the lower one)
 

System presentation: see ZDTV report
               Examples (Applications) of Human Computer Interaction
 
  • Manipulation of Artifical Objects (MPEG) (grasping of objects on the screen) - after an initial teaching phase the system allows manipulations of artifical objects
  • Vision-Based Interfaces(MPEG)(calculator application)
    		•
  •                             
    		• Color based feature selection + tracking 
    (MPEG from ICRA99 in Detroit)
    (MPEG of color tracking based on XVision)
    		Laser-Based Navigation based on  XVision and 
     
     

     HTML-slides about Laser-Based Map Generation
    (see example(MPEG)  of Visual Servoing method for mobile navigation)

    Vision-based control
    work together with UIUC group
    		Positive (objects) and negative (gaps) obstacle detection from stereo vision.
    One of the original images (left), calculated disparity image (right) and detected obstacle (bottom).
    In the MPEG movie  the box is recognized as an obstacle, but not the newspaper presented later.
    		Vision-based obstacle avoidance used for safe navigation of the mobile robot ( MPEG movie )
                         
    		Omnidirectional navigation for mobile systems. 
       - Vision Based Navigation
       - Virtual Joystick ( MPEG movie )

               
    		Vision-Based Control for Robocup
    A few Robocup impressions from Seattle 2001
