1. Identification of spectral features differentiating fungal strains in infrared absorption spectroscopic images
University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisationAbstract : 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. Construction and development of a low-cost hyperspectral imaging system
University essay from Umeå universitet/Institutionen för fysikAbstract : 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. 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

4. 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

5. Reconstruction of Hyperspectral Images Using Generative Adversarial Networks
University essay from Linköpings universitet/ReglerteknikAbstract : Fast detection and identification of unknown substances is an area of interest for many parties. Raman spectroscopy is a laser-based method allowing for long range no contact investigation of substances. READ MORE
