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

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Babak Rasolzadeh; KTH.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 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. Effects of online advertising on children's visual attention and task performance during free and goal-directed internet use : A media psychology approach to children's website interaction and advert distraction

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Nils Holmberg; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2016]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; online advertising; children; website interaction; visual attention; distraction; cognitive load; eye-tracking; task-orientation; media effects; visual saliency; executive functions; media literacy; inhibitory control;

    Sammanfattning : Denna avhandling består av fyra delstudier som undersöker hur internetreklam påverkar barns visuella uppmärksamhet. Syftet med studierna var att ta reda på om barn distraherades av internetreklam när de interagerade med webbsidor med hjälp av en vanlig webbläsare. LÄS MER

    Sammanfattning : The evolution of advanced radio transmission technologies for third and future generation mobile radio systems has paved the way for the delivery of mobile multimedia services. This is further enabled through contemporary video coding standards, such as H. LÄS MER

  4. 4. Salient Region Detection Methods with Application to Traffic Sign Recognition from Street View Images

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Keren Fu; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; normalized cut; traffic sign recognition; saliency propagation; color distribution; continuous conditional random field; manifold; Salient region detection; adaptive graph edge weights; color contrast; geodesics;

    Sammanfattning : In the computer vision community, saliency detection refers to modeling the selective mechanism in human visual attentions. Outputs of saliency detection algorithms are called saliency maps, which represent conspicuousness levels of different scene areas. LÄS MER

  5. 5. Social causality in motion Visual bias and categorization of social interactions during the observation of chasing in infancy

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Martyna A. Galazka; Uppsala universitet.; [2017]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; social causality; motion; animacy perception; chasing goal-directed motion; heat-seeking; EEG; P400; Nc; spatial proximity; non-contact causality; functional specialization; specialized perception; evolution; Psychology; Psykologi;

    Sammanfattning : Since the seminal work of Fritz Heider and Marienne Simmel (1944) the study of animacy perception, or the perception and attribution of life from the motion of simple geometrical shapes has intrigued researchers. The intrigue for psychologists and vision scientists then and today centered on the stark disconnect between the simplicity of the visual input and the universal richness of the resulting percept.
