  1. 6. Detection of local motion artifacts and image background in laser speckle contrast imaging

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : Johannes Nyhlén; Märta Sund; [2023]
    Keywords : laser speckle contrast imaging; lsci; multi exposure laser speckle contrast imaging; melsci; machine learning; deep learning; statistical analysis; detection; local motion artifacts; 1D; 2D; 3D;

    Abstract : Laser speckle contrast imaging (LSCI) and its extension, multi-exposure laser speckle contrast imaging (MELSCI) are non-invasive techniques to monitor peripheral blood perfusion. One of the main drawbacks of LSCI and MELSCI in clinical use is that the techniques are sensitive to tissue movement. READ MORE

  3. 7. Detecting Images Outside Training Distribution for Fingerprint Spoof Detection

    University essay from Lunds universitet/Matematik LTH

    Author : Daniel Holmkvist; [2023]
    Keywords : Machine learning; Out-of-Distribution; Deep Neural Network; spoof detection; Neural Network; Mathematics and Statistics;

    Abstract : Artificial neural networks are known to run into issues when given samples that deviate from the training distribution, where the network may confidently provide an incorrect answer. Out-of-distribution detection methods aims to provide a solution to this issue, by detecting data that deviates from the distribution used to train the model. READ MORE

  4. 8. Persistent Homology : A Modern Application of Algebraic Topology in Data Analysis

    University essay from

    Author : Staffan Leijnse; [2023]
    Keywords : Data; Algebraic Topology; Persistent; Homology; Graded; Representation;

    Abstract : Topological data analysis emerged as a field in the 2000s and has proven very useful for examining the shape of data sets. Using persistent homology as their main methodology researchers has succesfully applied the theory presented in this paper to study as varied subjects as robot motion, brain connectivity, network theory, finger print analysis and computer vision.
