  1. 1. Visual Attention in Active Vision Systems : Attending, Classifying and Manipulating Objects

    Författare :Babak Rasolzadeh; Jan-Olof Eklundh; Ales Leonardis; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; visual attention; saliency map; compter vision; robotics; active vision; machine learning;

    Sammanfattning : This thesis has presented a computational model for the combination of bottom-up and top-down attentional mechanisms. Furthermore, the use for this model has been demonstrated in a variety of applications of machine and robotic vision. LÄS MER

  2. 2. Active Matter in a Critical State: From passive building blocks to active molecules, engines, and active droplets

    Författare :Falko Schmidt; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :active matter; nonequilibrium; self-assembly; microswimmers; nanomotors; optical tweezers; colloidal molecules; active droplets; critical Casimir forces;

    Sammanfattning : The motion of microscopic objects is strongly affected by their surrounding environment. In quiescent liquids, motion is reduced to random fluctuations known as Brownian motion. Nevertheless, microorganisms have been able to develop mechanisms to generate active motion. LÄS MER

  3. 3. Reinforcement Learning for Active Visual Perception

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

    Sammanfattning : 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.

  4. 4. On Performance Evaluation of Automotive Active Safety Systems

    Författare :Jonas Nilsson; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Semi-Autonomous Vehicles; Active Safety; Automotive; Augmented Reality.; Verification; Performance Evaluation; Decision Making;

    Sammanfattning : Road traffic accidents are a major global problem, annually causing over 1.2 million fatalities. To improve road safety, active safety systems support the driver by monitoring the vehicle and its surroundings, identifying hazardous situations and actively intervening to prevent or mitigate consequences of accidents.

  5. 5. Language Constructs for Safe Parallel Programming on Multi-Cores

    Författare :Johan Östlund; Tobias Wrigstad; Ludovic Henrio; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Programming Languages; Type Systems; Ownership Types; Concurrency; Parallelism; Actors; Active Objects; Structured Parallelism; Data Race-Freedom; Immutability; Uniqueness; Datavetenskap; Computer Science;

    Sammanfattning : The last decade has seen the transition from single-core processors to multi-cores and many-cores. This move has by and large shifted the responsibility from chip manufacturers to programmers to keep up with ever-increasing expectations on performance. LÄS MER
