  1. 11. Multispectral Imaging for Surveillance Applications

    University essay from Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska högskolan

    Author : Emil Riseby; Alexander Svensson; [2015]
    Keywords : multispectral; imaging; color; near-infrared; NIR; camera; calibration;

    Abstract : Silicon based sensors is a commonly used technology in digital cameras today. That has made such cameras relatively cheap and widely used. Unfortunately they are constructed to capture and represent image quality for humans. Several image applications work better without the restrictions of the visible spectrum. READ MORE

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

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

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

    Abstract : 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). READ MORE

  4. 13. Tree species classification using support vector machine on hyperspectral images

    University essay from Institutionen för systemteknik

    Author : Rikard Hedberg; [2010]
    Keywords : remote sensing; classification; support vector machine; maximum likelihood; principal component analysis; t-test; hyperspectral; multispectral;

    Abstract : For several years, FORAN Remote Sensing in Linköping has been using pulseintense laser scannings together with multispectral imaging for developing analysismethods in forestry. One area these laser scannings and images are used for is toclassify the species of single trees in forests. READ MORE

  5. 14. Fully Automatic Segmentation of White Matter Lesions from Multispectral Magnetic Resonance Imaging Data

    University essay from Institutionen för informationsteknologi

    Author : Shenshen Cui; [2010]
    Keywords : ;

    Abstract : A fully automatic white matter lesion segmentation method has been developed and evaluated. The method uses multispectral magnetic resonance imaging (MRI) data (T1,T2 and Proton Density). First fuzzy c means (FCM) was used to segment normal brain tissues (white matter,grey matter, and cerebrospinal fluid). READ MORE

  6. 15. Multispectral auroral imager and optical flow in aurora

    University essay from KTH/Rymd- och plasmafysik

    Author : Josef Höök; [2006]
    Keywords : ;

    Abstract : ”Auroral Structure and Kinetics” (ASK) is a multispectral auroral imager,developed and built by University of Southampton, UK, and Royal Institute ofTechnology, Sweden. The scientific objective of the instrument include characterisationof both high and low energy electron precipitation in aurora with highspatial and temporal resolution, and direct observation of plasma drifts in theionosphere.
