Spatio-Temporal Retinex-Inspired Envelope with Anisotropic Diffusion
(Master thesis, 2023)Flere algoritmer har tidligere blitt foreslått for spatiell fargekorrigering av bilder. En av disse algoritmene er STRESS, en Retinex-inspirert algortime som bruker stokastisk sampling for å lage omhyllingskurver. Denne ... -
Spatio-Temporal Retinex-Inspired Envelope with Stochastic Sampling: A Framework for Spatial Color Algorithms
(Journal article; Peer reviewed, 2011)The authors present a new framework for algorithms for a wide range of image enhancement and reproduction applications, named STRESS Spatio-Temporal Retinex-inspired Envelope with Stochastic Sampling. The algorithms work ... -
Spatio-Temporal Retinex-like Envelope with Total Variation
(Chapter; Peer reviewed, 2012)Many algorithms for spatial color correction of digital im- ages have been proposed in the past. Some of the most recently developed algorithms use stochastic sampling of the image in or- der to obtain maximum and minimum ... -
Spatio-temporal variation in large herbivore pressure in Norway during 1949-1999: has decreased grazing by livestock been countered by increased browsing by cervids?
(Journal article; Peer reviewed, 2011)During recent decades, rough livestock grazing has decreased markedly on unimproved land (i.e. natural and seminatural habitats) across most of Europe, whilst the number of wild cervids has increased. However, we still ... -
Spatio-temporal variation in moose-vehicle collisions: the effect of varying traffic intensity and light conditions
(Master thesis, 2013)In order to find effective mitigating measures against the large number of moose-vehicle collisions (MVCs) in the Nordic countries, it is important to learn more about the underlying mechanisms causing their spatio-temporal ... -
Spatio-temporal variation in phenotypic selection in a metapopulation of house sparrows (Passer domesticus)
(Master thesis, 2020)Romlig-tidsmessig variasjon i naturlig seleksjon kan ha viktige evolusjonære konsekvenser og innsamling av kunnskap om slik variasjon kan vise seg å være nyttig i bevaringsbiologi. Mange studier har målt romlig eller ... -
Spatio-temporal variation in sea state parameters along virtual ship route paths
(Peer reviewed; Journal article, 2021)The article presents a study investigating the level of variation in sea state parameters encountered by sailing ships crossing the oceans. The sea state parameters have been obtained from a reanalysis, in this case the ... -
Spatio-temporal weather maps: Extracting weather information along a travel route
(Master thesis, 2023)Denne masteroppgåva studerer romleg-temporale vêrkart. Meir spesifikt ser den på korleis ein kartbrukar kan få informasjon om vêret langs ei reiserute. Å få informasjon om vêret på ein enkel måte, når ein flytte seg i både ... -
Spatio-textual search on Spark
(Master thesis, 2017)The amount of spatially aware data is growing at a rapid rate, and challenges both processing and organizing such data is in focus in the scientific world and the industry. But spatial data seldom exists alone, usually ... -
Spatiotemporal Analysis and Comparison of Recent Land-Use and Land-Cover Changes in Norway and the Tibetan Plateau
(Master thesis, 2019)I takt med en økende befolkning øker også det økologiske fotavtrykket. Menneskepåvirkede endringer i landareal og bruken av disse har over tid resultert i lokal og global påvirkning i den grad at det nesten ikke finnes ... -
A spatiotemporal analysis of NO2 concentrations during the Italian 2020 COVID-19 lockdown
(Peer reviewed; Journal article, 2022)When a new environmental policy or a specific intervention is taken in order to improve air quality, it is paramount to assess and quantify—in space and time—the effectiveness of the adopted strategy. The lockdown measures ... -
Spatiotemporal aspects of pain in the general population; factors associated with the presence, development and distribution: Results from the HUNT2 and HUNT3 studies
(Doctoral theses at NTNU;2014:377, Doctoral thesis, 2014)Background Chronic musculoskeletal pain among adults is a common burden to the individual, the health care system, and society, and has been estimated to affect approximately onefifth of the European population. Such ... -
Spatiotemporal changes in vegetation following range expansion in Svalbard reindeer (Rangifer tarandus platyrhynchus)
(Master thesis, 2014)Store planteetere som introduseres til nye områder er i stand til å modifisere abundansen og sammensetting av vegetasjonen, spesielt i områder uten predatorer. I dette studiet undersøkte jeg endringer i vegetasjonen i tre ... -
Spatiotemporal diffusion of influenza A (H1N1): Starting point and risk factors
(Journal article; Peer reviewed, 2018)Influenza constitutes a major challenge to world health authorities due to high transmissibility and the capacity to generate large epidemics. This study aimed to characterize the diffusion process of influenza A (H1N1) ... -
Spatiotemporal Distribution of GABAA Receptor Subunits Within Layer II of Mouse Medial Entorhinal Cortex: Implications for Grid Cell Excitability
(Journal article; Peer reviewed, 2018)GABAergic parvalbumin-expressing (PV+) interneurons provide powerful inhibitory modulation of grid cells in layer II of the medial entorhinal cortex (MEC LII). However, the molecular machinery through which PV+ cells ... -
Spatiotemporal dynamics of avian communities
(Doctoral thesis, 2023)Community ecology is the study of how different species interact with each other and their environment in a given habitat. In the face of rapid biodiversity loss, community ecology studies are more important than ever. ... -
Spatiotemporal gait parameters for older adults – An interactive model adjusting reference data for gender, age, and body height
(Peer reviewed; Journal article, 2020)Introduction Since it is well documented that spatiotemporal gait parameters are affected by body size, it is of limited clinical value to compare individual scores against reference values without taking body size into ... -
