  1. 1. Image Quality Assessment Pipeline and Semi-Automated Annotation method for Synthetic Data

    Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Liam Le Tran; Edina Dedovic; [2023-10-24]
    Nyckelord :Facial Expression Recognition; FACS; Action Units; styleGAN2-ada; synthetic data; Image Quality Assessment; Multi-stage Pre-training; Pipeline Processing; Semi-automated Human Annotation;

    Sammanfattning : Predicting human emotions through facial expression, particularly in relation to medication field such as clinical trial settings, has garnered scientific interest in recent years due to significant understanding of the impact of treatment on emotions and social functioning. This thesis aims to improve performance of a FER model using large scale of synthetic data. LÄS MER

  3. 2. Despeckling Echocardiograms Using Generative Adversarial Networks

    Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Falk DIppel; [2023-10-23]
    Nyckelord :Generative adversarial network; deep learning; echocardiography; speckle noise; denoising; segmentation;

    Sammanfattning : Previous research had shown that generative adversarial networks (GANs) are capable of despeckling echocardiograms (echos) through image-to-image translation in real-time once trained. However, only limited information regarding the quality of denoised echos and explainability of useful GAN components is provided. LÄS MER

  4. 3. Research of appropriate luminance level of monitor screens in workplace

    Kandidat-uppsats, Högskolan Dalarna/Informatik

    Författare :Mengfei Wang; Shiqi Shu; [2023]
    Nyckelord :Screen brightness; Paradigm Color; Lighting conditions; Human eye preference; skärmens ljusstyrka; Paradigm färg; ljusförhållanden; Mänskliga ögonpreferenser;

    Sammanfattning : MÅL: Huvudsyftet med den här studien är att undersöka hur naturligt ljus påverkar det mänskliga ögats preferens för skärmens ljusstyrka när man tittar på en datorskärm. METODER: Tre experiment genomförs för att mäta i vilken utsträckning solljus förändrar bakgrundsljuset i form av solstrålning. LÄS MER

  5. 4. Image analysis of Light Optical Microscopy (LOM) images of metallurgical samples

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :David Håkansson; [2023]
    Nyckelord :;

    Sammanfattning : Processing metals in different ways often requires stringent quality control to ensure the quality of the processed metal. This master's thesis aims to develop methods for evaluating the quality of metals via image analysis rather than inspecting images manually as it traditionally has been done. LÄS MER

  7. 5. Initial Orbit Determination of Resident Space Objects From A Passive Optical Imaging System: : Application to Space Situational Awareness

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Jessica McKenna; [2023]
    Nyckelord :Space Situational Awareness; Space Science; Angles-Only Initial Orbit Determination;

    Sammanfattning : The probability of satellite collisions and disintegrations cluttering the near-Earth orbital environmentis ever-growing. This is especially true for the congested Low Earth Orbit (LEO) regime; once a critical density of objects is reached, a collisional cascading is projected to generate runaway growth of theorbital population.
