  2. 2. Spatio-Temporal Scale-Space Theory

    Författare :Daniel Fagerström; Jan-Olof Eklundh; Luc Florack; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Image analysis; Bildanalys;

    Sammanfattning : This thesis addresses two important topics in developing a systematic space-time geometric approach to real-time, low-level motion vision. The first one concerns measuring of image flow, while the second one focuses on how to find low level features. LÄS MER

  3. 3. Modelling calving and sliding of Svalbard outlet glaciers : Spatio-temporal changes and interactions

    Författare :Dorothée Vallot; Rickard Pettersson; Veijo Pohjola; Ken Mattsson; Tómas Jóhannesson; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; cryospheric science; glacier modelling; time-lapse imagery; undercutting; sliding inversion; discrete particle model; calving model; subglacial hydrology; sliding law; automatic detection method; calving events size and frequency; ocean interaction; melt water runoff; ice dynamics; ice flow model; Geovetenskap med inriktning mot naturgeografi; Earth Science with specialization in Physical Geography;

    Sammanfattning : Future sea level rise associated to global warming is one of the greatest societal and environmental challenges of tomorrow. A large part of the contribution comes from glaciers and ice sheets discharging ice and meltwater into the ocean and the recent worldwide increase is worrying. LÄS MER

  4. 4. Physical control of phytoplankton growth in the Baltic Sea : a multitude of spatio-temporal scales

    Författare :Sulev Nõmmann; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Fytoplankton;

    Sammanfattning : Shipboard systems have been used for concurrent quasi-continuous measurements ofparticle size distribution, Chi fluorescence, salt and temperature and meteorologicalparameters. A resolution from 100 m to basin-wide, supplemented with variousmeasurements at fixed stations made it possible to investigate biological- physical couplingsduring the vernal phytoplankton bloom of the two years 1985/86 and in a coastal area ofthe Baltic Sea.

  5. 5. Spatio-Temporal Pre-Processing Methods for Region-of-Interest Video Coding

    Författare :Linda S. Karlsson; Tingting Zhang; Mårten Sjöström; Youzhi Xu; Apostolos Georgakis; Mittuniversitetet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Region-of-interest; video coding; pre-processing; spatio-temporal filters; Computer and systems science; Data- och systemvetenskap;

    Sammanfattning : In video transmission at low bit rates the challenge is to compress the video with a minimal reduction of the percieved quality. The compression can be adapted to knowledge of which regions in the video sequence are of most interest to the viewer. LÄS MER
