Hyper spectral data estimation from power dimensionality experimental imagingHyper spectral data estimation from power dimensionality experimental imaging Μεταπτυχιακή Διατριβή Master Thesis 2014-07-142014enWe report the first real time modular spectral and color imaging system based on the combination of snapshot spectral imaging, spectral estimation and color reproduction algorithms. A limited number of spectral bands are captured simultaneously, with the aid of specially designed camera, which are subsequently processed with spectral estimation algorithms to obtain a full spectrum per image pixel. We have succeeded to demonstrate complete spectral cube calculation and display of millions of spectra in real-time and to remove trade-off between spectral and spatial resolution. Besides accurate spectral mapping, our approach enables also reliable and device-independent color reproduction based on complete, per-pixel spectra. These achievements hold the promise to provide an indispensable tool in nondestructive analysis and in noninvasive diagnosis. http://creativecommons.org/licenses/by-nc-nd/4.0/Πολυτεχνείο Κρήτης::Σχολή Ηλεκτρονικών Μηχανικών και Μηχανικών ΥπολογιστώνIliou_Dimitrios_MSc_2014.pdfChania [Greece]Library of TUC2014-07-14application/pdf11.9 MBembargo Iliou Dimitrios Ηλιου Δημητριος Balas Costas Μπαλας Κωστας Garofalakis Minos Γαροφαλακης Μινως Digalakis Vasilis Διγαλακης Βασιλης Technical University of Crete Πολυτεχνείο Κρήτης Real time spectral imaging Digital image processing image processing digital techniques digital image processing Analysis, Spectrum Spectra Spectrochemical analysis Spectrochemistry Spectroscopy spectrum analysis analysis spectrum spectra spectrochemical analysis spectrochemistry spectroscopy
