  • High-Speed Feature Extraction in Sensor Coordinates for Laser Rangefinders 
    Alempijevic Alen (ARAA (Australian Robotics & Automation Association), 2004)
    The main contributions of this paper are two algorithms for extracting lines and comers present in the environment from information gathered by a laser rangefinder. The laser range scan is processed in its natural ...
  • Learning Navigational Maps by Observing Human Motion Patterns 
    O'Callaghan Simon; Singh Surya; Alempijevic Alen; Ramos Fabio (IEEE, 2011)
    Abstract¿Observing human motion patterns is informative for social robots that share the environment with people. This paper presents a methodology to allow a robot to navigate in a complex environment by observing pedestrian ...
  • Nonverbal Robot-Group Interaction Using an Imitated Gaze Cue 
    Kirchner Nathan; Alempijevic Alen; Dissanayake Gamini (ACM, 2011)
    Ensuring that a particular and unsuspecting member of a group is the recipient of a salient-item hand-over is a complicated interaction. The robot must effectively, expediently and reliably communicate its intentions to ...
  • Robust Lane Detection in Urban Environments 
    Sehestedt Stephan; Kodagoda Sarath; Alempijevic Alen; Dissanayake Gamini (The Institute of Electrical and Electronic Engineers Inc (IEEE), 2007)
    Most of the lane marking detection algorithms reported in the literature are suitable for highway scenarios. This paper presents a novel clustered particle filter based approach to lane detection, which is suitable for ...
  • Towards an Enhanced Driver Situation Awareness System 
    Alempijevic Alen; Zhang Zhengzhi; Kodagoda Sarath; Donikian Ashod; Dissanayake Gamini; Sehestedt Stephan (The Institute of Electrical and Electronic Engineers Inc (IEEE), 2007)
    This paper outlines our current research agenda to achieve enhanced driver situation awareness. A novel approach that incorporates information gathered from sensors mounted on the neighboring vehicles, in the ...
  • Towards Improving Driver Situation Awareness at Intersections 
    Kodagoda Sarath; Alempijevic Alen; Sehestedt Stephan; Dissanayake Gamini (The Institute of Electrical and Electronic Engineers Inc (IEEE), 2007)
    Providing safety critical information to the driver is vital in reducing road accidents, especially at intersections. Intersections are complex to deal with due to the presence of large number of vehicle and pedestrian ...
