  1. 6. Camera Distortion Calibration through Fringe Pattern Phase Analysis

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Karl Karlsson; [2023]
    Nyckelord :fringe-pattern; distortion; monogenic signal; phase analysis;

    Sammanfattning : The goal of this thesis is to use fringe-pattern phase analysis to calibrate the distortion of a camera lens. The benefit of using this method is that the distortion can be calculated using data from each individual pixel and the methodology does not need any model. LÄS MER

  3. 7. Perron-Frobenius' Theory and Applications

    Kandidat-uppsats, Linköpings universitet/Algebra, geometri och diskret matematik; Linköpings universitet/Tekniska fakulteten

    Författare :Karl Eriksson; [2023]
    Nyckelord :Positive matrices; nonnegative matrices; Perron-Frobenius; linear dynamical systems; Leslie matrices; Markov chain; Google s PageRank algorithm; Positiva matriser; icke-negativa matriser; Perron-Frobenius; linjära dynamiska system; Leslie matris; Markov-kedja; Google s PageRank algoritm;

    Sammanfattning : This is a literature study, in linear algebra, about positive and nonnegative matrices and their special properties. We say that a matrix or a vector is positive/nonnegative if all of its entries are positive/nonnegative. First, we study some generalities and become acquainted with two types of nonnegative matrices; irreducible and reducible. LÄS MER

  4. 8. Fast Clock Synchronization for Large-Scale MEMS Ultrasonic Transducer Arrays

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Karl-Johan Karlsson; [2022]
    Nyckelord :clock synchronization; clock deskew; MEMS transducer; Delay line; Time-to-Digital conveter;

    Sammanfattning : In many systems today sensors or transmitters need to be read or controlled simultaneously. This thesis investigates a new architecture used for deskewing clock signals between multiple separated parts of a signal transmission system. LÄS MER

  5. 9. Causal Inference on Tactical Simulations using Bayesian Structure Learning

    Master-uppsats, Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Författare :Karl Lagerkvist Blomqvist; [2022]
    Nyckelord :Causal Inference; Bayesian Structure Learning; Do-Calculus; Tactical Simulations; Kausal Inferens; Bayesiansk Strukturinlärning; Do-Calculus; Taktiska Simuleringar;

    Sammanfattning : This thesis explores the possibility of using Bayesian Structure Learning and Do-Calculus to perform causal inference on data from tactical combat simulations provided by Saab. A four-step approach is considered whose first step is to find a Bayesian Network from the data using Bayesian Structure Learning and Probability Distribution Fitting. LÄS MER

  7. 10. Rendering Photorealistic Images of Sticky Notes in Synthesized Indoor Environments : Creating a synthetic dataset in procedurally genererated environments

    Master-uppsats, Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakulteten

    Författare :Karl Eknefelt; [2022]
    Nyckelord :Computer vision; Computer graphics; Synthetic; Procedural; Dataset;

    Sammanfattning : This thesis is about creating a synthetic data generation pipeline to replace the manual process of adding bounding box-labeled images of sticky notes to an evaluation dataset of a traditional CV algorithm. With this approach, 462 labeled 12 megapixel-images in 55 different, procedurally varied scenes were generated in 8 hours using a MacBook M1 Max laptop. LÄS MER
