  2. 1. Learning Multidimensional Signal Processing

    Author : Magnus Borga; Hans Knutsson; Josef Kittler; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The subject of this dissertation is to show how learning can be used for multidimensional signal processing, in particular computer vision. Learning is a wide concept, but it can generally be defined as a system’s change of behaviour in order to improve its performance in some sense. READ MORE

  4. 2. The Use of a Bayesian Neural Network Model for Classification Tasks

    Author : Anders Holst; Josef Kittler; Stockholms universitet; []

    Abstract : .... READ MORE

  5. 3. Improving Image Classification Performance using Joint Feature Selection

    Author : Heydar Maboudi Afkham; Stefan Carlsson; Josef Kittler; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Image Classification; Latent Variable Models; Computer Science; Datalogi;

    Abstract : In this thesis, we focus on the problem of image classification and investigate how its performance can be systematically improved. Improving the performance of different computer vision methods has been the subject of many studies. READ MORE

  6. 4. Urban Change Detection Using Multitemporal SAR Images

    Author : Osama Yousif; Yifang Ban; Lorenzo Bruzzone; KTH; []
    Keywords : 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;

    Abstract : 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.

  7. 5. Change Detection Using Multitemporal SAR Images

    Author : Osama Yousif; Yifang Ban; Lorenzo Bruzzones; KTH; []
    Keywords : 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;

    Abstract : 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.
