  2. 11. Vision-based Human Detection from Mobile Machinery in Industrial Environments

    Author : Rafael Mosberger; Achim J. Lilienthal; Henrik Andreasson; Jürgen Gall; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Industrial Safety; Mobile Machinery; Human Detection; Computer Vision; Machine Learning; Infrared Vision; High-visibility Clothing; Reflective Markers; Datavetenskap; Computer Science;

    Abstract : The problem addressed in this thesis is the detection, localisation and tracking of human workers from mobile industrial machinery using a customised vision system developed at Örebro University. Coined the RefleX Vision System, its hardware configuration and computer vision algorithms were specifically designed for real-world industrial scenarios where workers are required to wear protective high-visibility garments with retro-reflective markers.

  5. 13. Bird Vision: Spatial acuity and colour discrimination in bright and dim light

    Author : Olle Lind; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Animal vision; Visual ecology; Colour vision; Spatial acuity; Spatial contrast sensitivity; Dim light; Visual modelling; Behavioural experiments; Birds; Psittaciformes;

    Abstract : Birds use vision to guide navigation, foraging and mate choice, and studies of the limitations in bird visual perception are most helpful for the understanding of bird ecology. Here, I present four studies of bird vision in bright and dim light. READ MORE

  6. 14. On Robot Control using Range Sensors : with Special Reference to Active Uncertainty Reduction

    Author : Bernt Nilsson; Aarne Halme; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Robot Gripping and Docking; Gripper-Object Feedback; Non-contact Sensing; Laser Ranging; Flexible Arm; Mobile Robot; Probing; Dual Control; LQG-Feedback;

    Abstract : This thesis addresses the problem of positioning robots relative to objects in the surrounding work space. The object's position and orientation (posture) are measured using a non-contact sensor on-board the robot. For gripping/docking tasks the goal posture is specified relative to the object and not in a fixed coordinate system of the robot. READ MORE

  7. 15. Embodied Visual Object Recognition

    Author : Marcus Wallenberg; Per-Erik Forssén; Michael Felsberg; Aleš Ude; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; object recognition; machine learning; computer vision;

    Abstract : Object recognition is a skill we as humans often take for granted. Due to our formidable object learning, recognition and generalisation skills, it is sometimes hard to see the multitude of obstacles that need to be overcome in order to replicate this skill in an artificial system.
