  1. 1. Identification of spectral features differentiating fungal strains in infrared absorption spectroscopic images

    University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik

    Author : Dejan Stancevic; [2022]
    Keywords : Physics and Astronomy;

    Abstract : There are many unknowns regarding the interaction between fungi and their surroundings. In this project, we took a closer look at hyperspectral images of several fungal strains on two different substrates. The project mainly consisted of developing a code for the classification of fungal strains and the extraction of information from it. READ MORE

  2. 2. Construction and development of a low-cost hyperspectral imaging system

    University essay from Umeå universitet/Institutionen för fysik

    Author : Nikita Grigoriev; [2022]
    Keywords : Hyperspectral Imaging; Pushbroom;

    Abstract : Quantification of spectral data is of great interest in many fields of science, since it can provide further insight into other properties of an object. However, traditional cameras are usually made to image the world in a similar fashion as to how we see it, wherefore they are usually not fit to record nor measure further spectral information.

  3. 3. Accelerating MCR-ALS decomposition of hyperspectral images using k-means clustering

    University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik

    Author : Eric Kull; [2022]
    Keywords : k-means; clustering; MCR-ALS; hyperspectral image; Physics and Astronomy;

    Abstract : 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

  4. 4. A comparison of different machine learning algorithms applied to hyperspectral data analysis

    University essay from Umeå universitet/Institutionen för fysik

    Author : Axel Vikström; [2021]
    Keywords : ;

    Abstract : 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

  5. 5. Reconstruction of Hyperspectral Images Using Generative Adversarial Networks

    University essay from Linköpings universitet/Reglerteknik
