  1. 1. Focus of attention and gaze control for robot vision

    Författare :Carl-Johan Westelius; Hans Knutsson; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This thesis deals with focus of attention control in active vision systems. A framework for hierarchical gaze control in a robot vision system is presented, and an implementation for a simulated robot is described. LÄS MER

  3. 2. Preattentive gaze control for robot vision

    Författare :Carl-Johan Westelius; Linköpings universitet; []
    Nyckelord :Robot vision; Resolution pyramids; Phase-based disparity estimation; Focus of attention; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : A framework for a hierarchical approach to gaze control of a robot vision system is presented, and a implementation on a simulated robot is described. The robot is equipped with a heterogeneous sampled imaging system, a fovea, resembling the varying resolution in a human retina. LÄS MER

  4. 3. Picture Viewing and Picture Description: Two Windows on the Mind

    Författare :Jana Holsanova; Kognitionsvetenskap; []
    Nyckelord :HUMANIORA; HUMANITIES; discourse hierarchy; picture description; vision; picture viewing; information flow; discourse segmentation; discourse analysis; coherence; semantics; spatial and temporal relations; cognitive science; linguistics; cognitive linguistics; psycholinguistics; speech; cognition; multimodal communication; mental processes; eye movement protocol; focus of attention; spoken language protocol; information processing; scene perception; areas of interest;

    Sammanfattning : In this thesis, I connect two disciplines, linguistics and vision research, and combine two methods, spoken language protocols and eye movement protocols, in order to cast light on the underlying cognitive processes. In a series of studies, I investigate the processual aspects of picture viewing and picture description. LÄS MER

  5. 4. Discrete Scale-Space Theory and the Scale-Space Primal Sketch

    Författare :Tony Lindeberg; Jan-Olof Eklundh; Jan. J Koenderink; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Computer vision; low-level processing; scale-space; diffusion; Gaussian filtering; discrete smoothing; primal sketch; segmentation; descriptive elements; scale detection; image structure; focus-of-attention; tuning low-level processing; blob detection; edge detection; edge focusing; histogram analysis; junction classification; perceptual grouping; texture analysis; critical points; classification of blob events; bifurcations; drift velocity; density of local extrema; multi-scale representation; digital signal processing; Computer Science; Datalogi;

    Sammanfattning : This thesis, within the subfield of computer science known as computer vision, deals with the use of scale-space analysis in early low-level processing of visual information. The main contributions comprise the following five subjects:The formulation of a scale-space theory for discrete signals. LÄS MER

  7. 5. Cykler och loopar i Salongen : En studie av återkoppling i frisörklassrummet

    Författare :Anna Öhman; Hector Pérez Prieto; Anna Lena Göransson; Marie Karlsson; Anders Jönsson; Karlstads universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Feedback; assessment; classroom; multimodal social semiotics; communication; vocational education; knowing; Återkoppling; bedömning; yrkesutbildning; multimodal socialsemiotik; kommunikation; kunnande; klassrum; Pedagogiskt arbete; Educational Work;

    Sammanfattning : The interest in this empirical study aims at assessment, more precisely feedback as part of ordinary activities within hairdressing education. The study investigates feedback practices related to assessment of knowing during production, with focus on communication between student and teacher. LÄS MER
