Accelerating support vector machines for remote platforms by increasing sparsity
Garrett, Joseph; Singh, N; Johansen, Tor Arne; Necoara, Ion (Peer reviewed; Journal article, 2022)The support vector machine (SVM) classification algorithm often achieves quite high accuracy on hyperspectral images, even when trained on small amounts of data. However, SVMs can still be computationally expensive relative ... -

Clustering and Classification of hyperspectral images on the HYPSO CubeSat
Danielsen, Aksel (Master thesis, 2021)NTNU SmallSat Lab utvikler HYPSO, en kubesatellitt som skal overvåke havet ved bruk av et hyperspektralt kamera. Prosesseringen av hyperspektrale bilder ombord blir gjort serielt i en prosesseringskjede som ble utviklet ... -
Comparing pre- and post-launch images from the HYPSO-1 cubesat hyperspectral imager
Henriksen, Marie Bøe; Garrett, Joseph; Johansen, Tor Arne; Sigernes, Fred (Journal article, 2022)HYPSO-1, a 6U cubesat carrying a hyperspectral imaging payload for ocean color observation, was launched in January 2022. During the commissioning and validation phases, the satellite and payload performance were tested. ... -
Density classification of marine seagrass (Zostera marina) for blue carbon estimation using drones and Convolution Neural Networks
Borger, Casper (Master thesis, 2024)Denne masteroppgaven undersøker bruk av konvolusjonelle nevrale nettverk for estimering av blå karbon basert på data samlet fra dronebilder og feltundersøkelser. Studien konsentrerer seg om en sjøgressart kalt ålegras ... -
