1. 1. Heart- and Sapwood Segmentation on Hyperspectral Images using Deep Learning

   University essay from Linköpings universitet/Institutionen för systemteknik

   Author : Samuel Hallin; Simon Samnegård; [2023]
   Keywords : Computer Vision; Hyperspectral Imaging; Heartwood; Sapwood; Deep Learning; Segmentation; Dimensionality Reduction; PCA; PLS; SVM; U-NET; U-within-U-Net;

   Abstract : For manufacturers in the wood industry, an important way to make the production more effective is to automate the process of detecting defects and different attributes on boards. One important attribute on most boards is heartwood and sapwood. READ MORE

3. 2. 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

4. 3. Machine learning methods for seasonal allergic rhinitis studies

   University essay from Linköpings universitet/Statistik och maskininlärning

   Author : Zijie Feng; [2021]
   Keywords : Machine learning; Seasonal allergic rhinitis; Random forest; Partial least squares discriminant analysis; Bootstrap; Cubic smoothing splines; Single-cell RNA sequencing;

   Abstract : Seasonal allergic rhinitis (SAR) is a disease caused by allergens from both environmental and genetic factors. Some researchers have studied the SAR based on traditional genetic methodologies. As technology develops, a new technique called single-cell RNA sequencing (scRNA-seq) is developed, which can generate high-dimension data. READ MORE

5. 4. Bayes Factors for the Proposition of a Common Source of Amphetamine Seizures.

   University essay from Linköpings universitet/Statistik och maskininlärning

   Author : Yash Pawar; [2021]
   Keywords : Amphetamine Data; LDA; PLS-DA; NSC; Gaussaianize; pairwise ratios;

   Abstract : This thesis sets out to address the challenges with the comparison of Amphetamine material in determining whether they originate from the same source or different sources using pairwise ratios of peak areas within each chromatogram of material and then modeling the difference between the ratios for each comparison as a basis for evaluation. The evaluation of an existing method that uses these ratios to determine the sum of significant differences between each comparison of material that is provided is done. READ MORE

6. 5. NEAR-INFRARED SPECTROSCOPY FOR REFUSE DERIVED FUEL : Classification of waste material components using hyperspectral imaging and feasibility study of inorganic chlorine content quantification

   University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

   Author : Martin Ševčík; [2019]
   Keywords : near-infrared spectroscopy; NIR; municipal solid waste; MSW; refuse derived fuel; RDF; classification; chemometrics; machine learning; artificial neural network; radial basis neural network; high-temperature corrosion; chlorine; waste to energy;

   Abstract : This degree project focused on examining new possible application of near-infrared (NIR) spectroscopy for quantitative and qualitative characterization of refuse derived fuel (RDF). Particularly, two possible applications were examined as part of the project. READ MORE
