  1. 1. Low-energy radar for handheld IR-cameras : Using mmWave radar as a complement for Multi Spectral Dynamic Imaging in handheld cameras

    Kandidat-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Sarwin Abdullah; [2023]
    Nyckelord :;

    Sammanfattning : The aim of this project is to assess whether a low energy radar, more specifically the mmWave radar from Acconer could be used as a complement to the handheld cameras from FLIR, in order to improve its performance, in particular the alignment of visual and infra-red image. The specific camera used for this project is a FLIR C5 IR-camera. LÄS MER

  3. 2. Multi-spectral X-ray imaging with a laser-plasma accelerator

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Andrea Angella; [2022]
    Nyckelord :Multi-spectral imaging; single-photon counting; X-ray absorption spectroscopy; XAS; LWFA; laser-wakefield acceleration; K-edge; imaging; metal-detection algorithm; Physics and Astronomy;

    Sammanfattning : This master thesis focuses on the creation of an algorithm to perform multispectral imaging of a metallic target using X-rays. The generation of an ultrashort high-power low-divergent X-ray beam is performed by means of a Ti:Sapphire laser driven wake-field plasma accelerator. LÄS MER

  4. 3. Development of 3D Spectrometry using Compressive Sensing

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Författare :Jonas Ravelid; [2018]
    Nyckelord :Compressive Sensing; 3D; Spectroscopy; Imaging; Multi-spectral; CS; TwIST; Mask; Physics and Astronomy;

    Sammanfattning : Multi-spectral imaging is a powerful approach in spectral analysis of objects with spatial details. However, such approaches are most often time consuming and experimentally complex since both spectral and spatial information in two dimensions are to be resolved. LÄS MER

  5. 4. The potential of support vector machine classification of land use and land cover using seasonality from MODIS satellite data

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Florian Sallaba; [2011]
    Nyckelord :geography; geomatics; remote sensing; MODIS; support vector machine; phenology; TIMESAT; geografi; geomatik; fjärranalys; fenologi; Earth and Environmental Sciences;

    Sammanfattning : With respect to climate change it is necessary to study land use and land cover (LULC) and their changes. LULC are related directly and indirectly to climatic changes such as rising temperatures that trigger earlier onset of vegetation growing seasons (IPCC 2007). LÄS MER

  7. 5. Multispectral Image Acquisition

    Master-uppsats, Institutionen för teknik och naturvetenskap; Tekniska högskolan

    Författare :Atheer Wahham; [2006]
    Nyckelord :;

    Sammanfattning : The purpose of this project was to develop control software for a multi-spectral imaging system. The multi-spectral imaging system used by the colour Lab consists of a camera (Alta USB camera) and a filter (VariSpec liquid crystal tuneable filter). LÄS MER
