  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

  3. 3. Enhancement of Salient Image Regions for Visual Object Detection

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

    Författare :Keren Fu; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geodesic distance; graph spectral decomposition; video processing; visual attention; color contrast and distribution; propagation; salient region; figure-ground segmentation;

    Sammanfattning : Salient object/region detection aims at finding interesting regions in images and videos, since such regions contain important information and easily attract human attention. The detected regions can be further used for more complicated computer vision applications such as object detection and recognition, image compression, content-based image editing, and image retrieval.

  4. 4. Modelling Perceptual Quality and Visual Saliency for Image and Video Communications

    Detta är en avhandling från Karlskrona : Blekinge Institute of Technology

    Författare :Ulrich Engelke; Blekinge Tekniska Högskola.; [2010]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    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

  5. 5. 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
