  1. 21. Microsatellite Constellation for Wildfire Monitoring

    Master-uppsats, KTH/Geoinformatik

    Författare :Citlali Bruce Rosete; [2022]
    Nyckelord :microsatellite; shortwave infrared sensor; active fire monitoring; burned area detection; satellite constellation; mikrosatellit; kortvågig infraröd sensor; aktiv brandövervakning; detektion av brandhärjat område; satellitkonstellation;

    Sammanfattning : I flera års tid har antalet svåra och okontrollerade skogsbränder ökat i antal. Det finns ett behov av att detektera skogsbränder med hjälp av satelliter som har högre tidsupplösning samt högre geometrisk upplösning än de satelliter som är i bruk idag. LÄS MER

  3. 22. Improving segmentation of agricultural patterns in aerial imagery using near-infrared images

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Jonathan Lindén; [2022]
    Nyckelord :;

    Sammanfattning : Climate change and loss of biodiversity are currently two of the most imminent global threats caused in part by agricultural practices. With the rise of computer vision, the use of precision farming has become a viable technique to optimise food production. LÄS MER

  4. 23. Prediction of flue gas properties using artificial intelligence : Application of supervised machine learning by utilization of Near-Infrared Spectroscopy on solid biofuels

    Uppsats för yrkesexamina på avancerad nivå, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Bashe Abdirahman Hussein; Emran Samimi; [2022]
    Nyckelord :Artificial Intelligence; Machine learning; Near-Infrared spectroscopy; Solid biofuels; Fuel element; Flue gas composition; CCS;

    Sammanfattning : This degree project studies implementation and comparison of different AI models to predict (1) solid biofuel elements including carbon, hydrogen, nitrogen, and oxygen as well as moisture content, ash content, and higher heating value (HHV) of the fuel and (2) flue gas compositions such as concentration of carbon dioxide, carbon monoxide, nitrogen, nitrogen oxides, and water content using near-infrared spectroscopy and chemometric approaches. The study executes these predictions by simulating the operation of a combined heat and power plant (CHP) that is equipped with carbon capture and storage (CCS). LÄS MER

  5. 24. Exploring Diversity of Spectral Data in Cloud Detection with Machine Learning Methods : Contribution of Near Infrared band in improving cloud detection in winter images

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Nakita Sunil Oza; [2022]
    Nyckelord :Remote sensing; Multispectral imaging; Cloud detection; Data diversity; Deep learning; Fjärranalys; Multispektral bildbehandling; Molndetektion; Datadiversitet; Djupinlärning;

    Sammanfattning : Cloud detection on satellite imagery is an essential pre-processing step for several remote sensing applications. In general, machine learning based methods for cloud detection perform well, especially the ones based on deep learning as they consider both spatial and spectral features of the input image.

  7. 25. Construction and development of a low-cost hyperspectral imaging system

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Nikita Grigoriev; [2022]
    Nyckelord :Hyperspectral Imaging; Pushbroom;

    Sammanfattning : Quantification of spectral data is of great interest in many fields of science, since it can provide further insight into other properties of an object. However, traditional cameras are usually made to image the world in a similar fashion as to how we see it, wherefore they are usually not fit to record nor measure further spectral information.
