  1. 1. Urban Change Detection Using Multitemporal SAR Images

    Författare :Osama Yousif; Yifang Ban; Lorenzo Bruzzone; KTH; []
    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.

    Sammanfattning : Silk-weaving in Sweden during the 19th century. Textiles and texts - An evaluation of the source material. With the rich material available, 19th century silk-weaving invites to studies on industrialisation processes. LÄS MER

  4. 3. Multitemporal Spaceborne Polarimetric SAR Data for Urban Land Cover Mapping

    Författare :Xin Niu; Yifang Ban; Laurent Ferro-Famil; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; RADARSAT-2; Spaceborne; Polarimetric SAR; Urban Land cover; Object-based Rule-based Classification; Support Vector Machines; Contextual; Stochastic Expectation-Maximization; Markov Random Field.;

    Sammanfattning : Urban land cover mapping represents one of the most important remote sensing applications in the context of rapid global urbanization. In recent years, high resolution spaceborne Polarimetric Synthetic Aperture Radar (PolSAR) has been increasingly used for urban land cover/land-use mapping, since more information could be obtained in multiple polarizations and the collection of such data is less influenced by solar illumination and weather conditions.

  5. 4. Heuristisk analys med Diderichsens satsschema - Tillämpningar för svensk text : Heuristic Analysis with Diderichsen’s Sentence Schema – Applications for Swedish Text

    Författare :Kenneth Wilhelmsson; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; Diderichsens nordiska satsschema; positionsgrammatik; fältgrammatik; licensieringstekniker; Stockholm Umeå Corpus; schemaparsning; rangbaserad chunkning; spetsställning; parafrasgenerering; frågegenerering; naturligt språk-frågesystem; svenska WordNet;

    Sammanfattning : A heuristic method for parsing Swedish text, heuristic schema parsing, is described and implemented. Focusing on main clause (primary) analysis, a collection of licensing techniques for removing non-primary verb candidates is employed, leaving e.g. LÄS MER

  7. 5. Satellite Monitoring of Urbanization and Indicator-based Assessment of Environmental Impact

    Författare :Dorothy Furberg; Yifang Ban; Xiaojun Yang; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Urbanization; remote sensing; land-cover classification; landscape metrics; environmental indicators; environmental impact; ecosystem services; green infrastructure; habitat network analysis; Greater Toronto Area; Stockholm; Shanghai; urbanisering; fjärranalys; marktäckeklassificering; landskapsnyckeltal; miljöindikatorer; miljöpåverkan; ekosystemtjänster; grön infrastruktur; habitat nätverksanalys; Greater Toronto Area; Stockholm; Shanghai; Geodesy and Geoinformatics; Geodesi och geoinformatik; Geoinformatik; Geoinformatics;

    Sammanfattning : As of 2018, 55% of the world population resides in urban areas. This proportion is projected to increase to 68% by 2050 (United Nations 2018). The Stockholm region is no exception to this urbanizing trend: the population of Stockholm City has risen by 28% since the year 2000. LÄS MER
