  2. 1. Interactive Perception : From Scenes to Objects

    Author : Niklas Bergström; Danica Kragic; Yiannis Aloimonos; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis builds on the observation that robots, like humans, do not have enough experience to handle all situations from the start. Therefore they need tools to cope with new situations, unknown scenes and unknown objects. In particular, this thesis addresses objects. READ MORE

  4. 2. Off-line Foveated Compression and Scene Perception: An Eye-Tracking Approach

    Author : Marcus Nyström; Humanistlaboratoriet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gaze prediction; off-line foveation; scene perception; eye-tracking; compression;

    Abstract : With the continued growth of digital services offering storage and communication of pictorial information, the need to efficiently represent this information has become increasingly important, both from an information theoretic and a perceptual point of view. There has been a recent interest to design systems for efficient representation and compression of image and video data that take the features of the human visual system into account. READ MORE

  5. 3. Reinforcement Learning for Active Visual Perception

    Author : Aleksis Pirinen; Mathematical Imaging Group; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; computer vision; reinforcement learning; deep learning; active vision; object detection; human pose estimation; semantic segmentation;

    Abstract : Visual perception refers to automatically recognizing, detecting, or otherwise sensing the content of an image, video or scene. The most common contemporary approach to tackle a visual perception task is by training a deep neural network on a pre-existing dataset which provides examples of task success and failure, respectively.

  6. 4. A Model of Driver Perception and Action in Intersections

    Author : Anna Bjelkemyr; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; intersection; vehicle heading; driving; behavior; driver; perception; eye movement; anticipate;

    Abstract : The objective of the research presented in this thesis is to describe driver behavior while approaching, entering and exiting an intersection. To fulfill this objective, two semi-naturalistic studies were conducted where ten driver participants drove a test vehicle through a three-way intersection repeatedly, driving straight, turning left, and turning right in a total of six possible passes.

  7. 5. Vision Based Perception for Mechatronic Weed Control

    Author : Björn Åstrand; David Slaughter; Högskolan i Halmstad; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Vision-based perception; Plant recognition; Row following; Weed Control; Mechatronics in agriculture; Mobile robots;

    Abstract : The use of computer-based signal processing and sensor technology to guide and control different types of agricultural field implements increases the performance of traditional implements and even makes it possible to create new ones. This thesis increases the knowledge on vision-based perception for mechatronic weed control. READ MORE
