Assessment of models predicting the maximum surface temperature in an urban setting using VIS/NIR/IR imaging from UAVs
Vukovic, Marija (Master thesis, 2018)Investigating surface temperature of the materials in urban settings is an important way of analyzing how urban heat islands can be mitigated. The present thesis investigates models for prediction of the maximum surface ... -
Automation of the labeling of images of sugar beet cultivation with hyperspectral imaging
Jäkel, Annika (Master thesis, 2020)The objective of this thesis was to develop an automated labeling system for RGB images (red green blue) of sugar beet and weed plants with the help of multispectral imaging. 863 image pairs of sugar beet and 18 weed ... -
Beregning av biomasse ved hjelp av multispektral laser
Ceballos, Kristoffer Mauricio Valderrama (Master thesis, 2018)I dette prosjektet her jeg beregnet biomasse til trær fra felt arbeid og fra laserdata. Gjennom dette prosjektet har jeg belyst temaer som er relevant for estimering av biomasse, og hvilke metoder og teknikker som er ... -
Bestemmelse av trefuktighet for gran (Picea abies) i en tretørkingsprosess ved bruk av hyperspektrale bilder
Wold, Julius (Master thesis, 2022)Fuktighet er en sentral egenskap til trevirke og spesielt under tørkingen er nøyaktig bestemmelse av fuktighet viktig. Hyperspektrale metoder er tidligere vist å kunne brukes til predikering av flere viktige egenskaper til ... -
Brick wall analysis by photogrammetry and image processing techniques
Johnsen, Espen (Master thesis, 2018)Deterioration of brick wall buildings can be seen as an effect from years of exposure to wind and weather. For example, through repeated freeze-thaw cycles, structural damage of the bricks might occur. In this thesis a ... -
Controlled infrared heating of an artic meadow: challenge in the vegetation establishment stage
Moni, Christophe; Silvennoinen, Hanna Marika; Kimball, Bruce A.; Fjelldal, Erling; Brenden, Marius; Burud, Ingunn; Flø, Andreas Svarstad; Rasse, Daniel (Journal article; Peer reviewed, 2019)Background: Global warming is going to affect both agricultural production and carbon storage in soil worldwide. Given the complexity of the soil-plant-atmosphere continuum, in situ experiments of climate warming are ... -
Defect related radiative recombination in mono-like crystalline silicon wafers
Bergan, Simen (Master thesis, 2016-08-31)The aim of this work was to investigate defect related luminescence emission in four mono-like silicon wafers. The seed-assisted silicon ingot is built by six Czochralski silicon slabs, with nine seed junctions. The ... -
Defects in multicrystalline Si wafers studied by spectral photoluminescence imaging, combined with EBSD and dislocation mapping
Mehl, Torbjørn; Di Sabatino Lundberg, Marisa; Adamczyk, Krzysztof; Burud, Ingunn; Olsen, Espen (Journal article; Peer reviewed, 2016) -
Estimation of phosphorus-based flame retardant in wood by hyperspectral imaging—a new method
Stefansson, Petter; Burud, Ingunn; Thiis, Thomas Kringlebotn; Gobakken, Lone; Larnøy, Erik (Journal article; Peer reviewed, 2018)It is recognised that flame retardant chemicals degrade and leach out of flame-protected wood claddings when exposed to natural weathering. However, the ability to survey the current state of a flame retardant treatment ... -
Evaluering av maskinlæring brukt til endringsdeteksjon av arealtyper i AR5 basert på flybilder
Munsterhjelm, Nicolai (Master thesis, 2021)Arealressurskartet AR5 ajourføres periodisk av Norsk institutt for bioøkonomi (NIBIO) ved bruk av flybilder. Maskinlæring kan øke kvaliteten på endringskartene og effektivisere ajourføringsprosessen. NIBIO har i løpet av ... -
