1. Accelerating MCR-ALS decomposition of hyperspectral images using k-means clustering
University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisationAbstract : A hyperspectral image may be decomposed into component spectra and their distri- bution in the image to simplify analysis by revealing underlying patterns and reducing the dimensionality of the image; this may be achieved by the algorithm MCR-ALS. However, the algorithm is time consuming, but could be accelerated by a data re- duction. READ MORE

2. A comparison of different machine learning algorithms applied to hyperspectral data analysis
University essay from Umeå universitet/Institutionen för fysikAbstract : Hyperspectral image analysis works with image data where each pixel contains hundreds of wavelengths acquired from spectral measurements. It is a growing field of research in the sciences and industries because it can distinguish visually similar objects. READ MORE

3. Pretraining a Neural Network for Hyperspectral Images Using Self-Supervised Contrastive Learning
University essay from Linköpings universitet/DatorseendeAbstract : Hyperspectral imaging is an expanding topic within the field of computer vision, that uses images of high spectral granularity. Contrastive learning is a discrim- inative approach to self-supervised learning, a form of unsupervised learning where the network is trained using self-created pseudo-labels. READ MORE

4. Image simulations of the mission Martian Moons eXploration
University essay from KTH/RymdteknikAbstract : Martian Moons eXploration is a JAXA-lead mission aiming at exploring the moons of Mars, Phobos and Deimos. The hyperspectral infrared camera provided by France should perform global mapping of Phobos at high resolution in order to characterize surface composition and therefore help determine the origins of the moons.

5. Detection and tracking of spruce seedlings in spatiospectral images
University essay from Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska högskolanAbstract : I projektet detekteras och följs granplantor i spatiospektrala bilder för att därefter skapa en hyperspektral datakub för av varje gran. För att detektera granarna prövas fyra metoder: manuell detektion, detektion med segmentering, detektion med SVM och detektion med neuralt nätverk. READ MORE
