    Email Print Request Permissions With respect to recent advances in remote sensing technologies, the spatial resolution of airborne and spaceborne sensors is getting finer, which enables us to precisely analyze even small objects on the Earth. This ...
  • Belart, Joaquín M. C.; Magnússon, Eyjólfur; Berthier, Etienne; Pálsson, Finnur; Adalgeirsdottir, Gudfinna; Jóhannesson, Tómas (Cambridge University Press (CUP), 2019-04-11)
    Mass-balance measurements of Icelandic glaciers are sparse through the 20th century. However, the large archive of stereo images available allows estimates of glacier-wide mass balance in decadal time steps since 1945. Combined with climate records, ...
  • Hong, Danfeng; Wu, Xin; Ghamisi, Pedram; Chanussot, Jocelyn; Yokoya, Naoto; Zhu, Xiao Xiang (Institute of Electrical and Electronics Engineers (IEEE), 2020-06)
    So far, a large number of advanced techniques have been developed to enhance and extract the spatially semantic information in hyperspectral image processing and analysis. However, locally semantic change, such as scene composition, relative position ...

    To date, most mass balance studies in Iceland have concentrated on the three largest ice caps. This study turns the focus toward smaller Icelandic glaciers, presenting geodetic mass-balance estimates for 14 of them (total area 1,005 km2 in 2017) from ...
  • Belart, Joaquín M. C. (University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2018-11-29)
    The mass balance of a glacier is strongly connected to climate. At high latitudes, mass balance is typically controlled by snow accumulation during the winter and the glacier ablation during the summer. In Iceland, direct mass balance observations ...
  • Benediktsson, Jon Atli; Ghamisi, Pedram; Martins, Fernando M. L.; Couceiro, Micael S. (IEEE, 2014)
    Hyperspectral remote sensing images contain hundreds of data channels. Due to the high dimensionality of the hyperspectral data, it is difficult to design accurate and efficient image segmentation algorithms for such imagery. In this paper, a new ...
  • Rasti, Behnood; Scheunders, Paul; Ghamisi, Pedram; Licciardi, Giorgio; Chanussot, Jocelyn (MDPI AG, 2018-03-20)
    Hyperspectral remote sensing is based on measuring the scattered and reflected electromagnetic signals from the Earth’s surface emitted by the Sun. The received radiance at the sensor is usually degraded by atmospheric effects and instrumental (sensor) ...
  • Gotz, Markus; Cavallaro, Gabriele; Geraud, Thierry; Book, Matthias; Riedel, Morris (Institute of Electrical and Electronics Engineers (IEEE), 2018-11-01)
    Component trees are region-based representations that encode the inclusion relationship of the threshold sets of an image. These representations are one of the most promising strategies for the analysis and the interpretation of spatial information ...
  • Benediktsson, Jon Atli; Cavallaro, Gabriele; Dalla Mura, Mauro; Plaza, Antonio (IEEE Geoscience & Remote Sensing Society, 2016)
    Remotely sensed images with very high spatial resolution provide a detailed representation of the surveyed scene with a geometrical resolution that, at the present, can be up to 30 cm (WorldView-3). A set of powerful image processing operators have ...

    The European Cooperation in Science and Technology (COST) Action ES1404 HarmoSnow, entitled, A European network for a harmonized monitoring of snow for the benefit of climate change scenarios, hydrology and numerical weather prediction (2014-2018) aims ...
  • Kizel, Fadi; Benediktsson, Jon Atli (MDPI AG, 2020-04-16)
    We propose an unmixing framework for enhancing endmember fraction maps using a combination of spectral and visible images. The new method, data fusion through spatial information-aided learning (DFuSIAL), is based on a learning process for the fusion ...
  • Stevens, Bjorn; Brogniez, Hélène; Kiemle, Christoph; Lacour, Jean-Lionel; Crevoisier, Cyril; Kiliani, Johannes (Springer Science and Business Media LLC, 2017-07-26)
    In situ, airborne and satellite measurements are used to characterize the structure of water vapor in the lower tropical troposphere—below the height, z∗, of the triple-point isotherm, T∗. The measurements are evaluated in light of understanding of how ...
