  2. 1. Hyperspectral Image Generation, Processing and Analysis

    Author : Hamed Hamid Muhammed; Ewert Bengtsson; Tommy Lindell; Erkki Oja; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bildanalys; hyperspectral imaging; colour filter mosaics; remote sensing; crop reflectance; surface water quality; disease severity; plant density; linear system of equations; waste water detection; chlorophyll a; suspended paticulate matter; weighted fixed neural networks; weighted incremental neural networks; camera spectrometer; Bildanalys; Image analysis; Bildanalys;

    Abstract : Hyperspectral reflectance data are utilised in many applications, where measured data are processed and converted into physical, chemical and/or biological properties of the target objects and/or processes being studied. It has been proven that crop reflectance data can be used to detect, characterise and quantify disease severity and plant density. READ MORE

  4. 2. Hyperspectral imaging for in-situ applications : Methods to improve the classification of materials using hyperspectral imaging

    Author : Muhammad Saad Shaikh; Benny Thörnberg; Mattias O'Nils; Jocelyn Chanussot; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis addresses several research questions related to in-situ hyperspectral imaging systems, proposes measurement methods for more accurate imaging, and examines the impact of the methods on material classification.First, the thesis investigates the possibility of successfully calibrating a hyperspectral imaging system using a low-cost PTFE reference.

  5. 3. Raman Spectroscopy and Hyperspectral Analysis of Living Cells Exposed to Nanoparticles

    Author : Linnea Ahlinder; Lars Österlund; Ioan Notingher; Uppsala universitet; []
    Keywords : Raman spectroscopy; Hyperspectral analysis; Multivariate data analysis; Nanotoxicology; Graphene oxide; Iron oxide; Titanium dioxide; Cells;

    Abstract : Nanoparticles, i.e. particles with at least one dimension smaller than 100 nm, are present in large quantities in ambient air and can also be found in an increasing amount of consumer products. It is known that many nanomaterials have physicochemical properties that differ from physicochemical properties of the same material in bulk size. READ MORE

  6. 4. Non-Invasive Monitoring of Architectural Heritage

    Author : Jenny Hällström; Bebyggelsevård; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; remote sensing; lidar; laser-induced fluorescence; documentation; hyperspectral; non invasive; non destructive; sustainable maintenance; conservation planning; monitoring; Coliseum; architectural conservation; restoration; Övedskloster; deterioration; Lateran Baptistery; stone; brick; thematic mapping; in situ; imaging; biodeteriogens;

    Abstract : The on-site documentation and examination of architectural heritage has presented challenges for traditional analysis methods in the form of, among other things, large complex structures, sites and environmental conditions. In recent years there has been growing interest in assessing progressing deterioration processes and material analysis, with an emphasis on sustainable conservation and maintenance planning.
