  1. 6. 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    Sammanfattning : Historical documents are a valuable source of cultural knowledge and can provide information about previous events, societies, beliefs, and cultures. They can serve as an excellent source for research in various fields including history, literature, linguistics, and anthropology. LÄS MER

  5. 9. Compact Soft X-Ray Microscopy: Image Processing and Instrumentation

    Författare :Heide Stollberg; Hans Hertz; Jürgen Thieme; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; X-ray microscopy; Physics; Fysik;

    Sammanfattning : Soft x-ray microscopy is a powerful technique for natural-contrast, high-resolution imaging of organic materials. This Thesis describes new instrumentational and new image-processing methods to improve the image quality of the compact x-ray microscope at the Biomedical & X-Ray Physics division at KTH. LÄS MER

  7. 10. Exact Minimizers in Real Interpolation : Characterization and Appliations

    Författare :Japhet Niyobuhungiro; Natan Kruglyak; Irina Asekritova; Fredrik Berntsson; Froduald Minani; Luboš Pick; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The main idea of the thesis is to develop new connections between the theory of real interpolation and applications. Near and exact minimizers for E–, K– and L–functionals of the theory of real interpolation are very important in applications connected to regularization of inverse problems such as image processing.
