  1. 1. Change Detection of the Unexpected : Enhancing change detection of the unexpected in a complex and high risk context – guiding visual attention in a digital display environment

    Detta är en avhandling från Uppsala : Institutionen för informatik och media

    Författare :Ulrik Spak; Uppsala universitet.; Försvarshögskolan.; [2015]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Människa-dator interaktion; Human-Computer Interaction; awareness; change blindness; change detection; command and control; display; feedback; human-computer interaction; inattentional blindness; monitoring; surveillance; visual cue; Ledningsvetenskap; Ledningsvetenskap;

    Sammanfattning : Change detection of objects and events in our visual surroundings is sometimes severely difficult, especially if these changes are unexpected. Such failures in change detection may cause huge malicious outcomes in contexts characterized by high levels of complexity and risk. LÄS MER

  2. 2. Urban Change Detection Using Multitemporal SAR Images

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

    Författare :Osama Yousif; KTH.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Change detection; High resolution; Image denoising; Kittler-Illingworth; MAP-MRF; Multitemporal SAR images; Nonlocal means; Object-based; Otsu; Outlier detection; Remote sensing; SAR speckle; Urban; Geodesy and Geoinformatics; Geodesi och geoinformatik;

    Sammanfattning : Multitemporal SAR images have been increasingly used for the detection of different types of environmental changes. The detection of urban changes using SAR images is complicated due to the complex mixture of the urban environment and the special characteristics of SAR images, for example, the existence of speckle.

  3. 3. Change Detection Using Multitemporal SAR Images

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

    Författare :Osama Yousif; KTH.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Change detection; ENVISAT ASAR; ERS-2 SAR; image denoising; Kittler-Illingworth algorithm; MAP-MRF classifier; modified ratio; multitemporal SAR images; nonlocal means NLM ; SAR speckle; urbanization;

    Sammanfattning : Multitemporal SAR images have been used successfully for the detection of different types of environmental changes. The detection of urban change using SAR images is complicated due to the special characteristics of SAR images—for example, the existence of speckle and the complex mixture of the urban environment.

  4. 4. Landscape from space : geographical aspects on scale, regionalization and change detection

    Detta är en avhandling från Stockholm : Deprtment of Human Geography, Stockholm University

    Författare :Ola Hall; Stockholms universitet.; Stockholms universitet.; [2002]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Regionalization; Scale; Change detection; Multiscale analysis; Objectspecific analysis; Watershed transformation; Landscape; Satellite data; Geography; Complex systems theory; Fuzzy set theory; Multicriteria-evaluation.; SOCIAL SCIENCES Business and economics Human geography; economic geography Human geography; SAMHÄLLSVETENSKAP Ekonomi Kulturgeografi; ekonomisk geografi Kulturgeografi; Human Geography; kulturgeografi;

    Sammanfattning : Landscapes are complex systems composed of multiscale hierarchically organized entities that interact within unique spatial and temporal scales. These interactions result in scaledependent spatial patterns that visually change depending upon the scale at which they are observed. LÄS MER

  5. 5. Detection and Tracking in Thermal Infrared Imagery

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Amanda Berg; Linköpings universitet.; Linköpings universitet.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; thermal; infrared; detection; tracking;

    Sammanfattning : Thermal cameras have historically been of interest mainly for military applications. Increasing image quality and resolution combined with decreasing price and size during recent years have, however, opened up new application areas. They are now widely used for civilian applications, e.g. LÄS MER
