  1. 1. Improving Brain Tumor Segmentation using synthetic images from GANs

    Master-uppsats, Linköpings universitet/Statistik och maskininlärning

    Författare :Aashana Nijhawan; [2021]
    Nyckelord :Image segmentation; Generative Adversarial Networks; GANs; Computer Vision; synthetic images; generator; discriminator; uncertainty estimation; deep neural networks; U-net; PGGAN;

    Sammanfattning : Artificial intelligence (AI) has been seeing a great amount of hype around it for a few years but more so now in the field of diagnostic medical imaging. AI-based diagnoses have shown improvements in detecting the smallest abnormalities present in tumors and lesions. This can tremendously help public healthcare. LÄS MER

  3. 2. Developing an emulator for 360° video : intended for algorithm development

    Master-uppsats, Linköpings universitet/Databas och informationsteknik

    Författare :Eric Lindskog; [2020]
    Nyckelord :VR; emulation; simulation; tools; 360°; video; streaming; DASH; HAS; QoE; MS-SSIM; SSIM; virtual; reality; fetching; VoD; bandwidth; MOS;

    Sammanfattning : Streaming 360° video has become more commonplace with content delivery services such as YouTube having support for it. By its nature, 360° video requires more bandwidth as only a fraction of the image is actually in view, while the user is expecting the same "in view" quality as with a regular video. LÄS MER

  4. 3. A Novel Perceptual Metric in Deep Learning

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Johanna Engman; Hanna Nilsson; [2020]
    Nyckelord :Loss function; Metric; Deep learning; Denoising; MRI reconstruction; U-net; Machine learning; Image Analysis; Mathematics and Statistics;

    Sammanfattning : Loss functions are a crucial part of image processing when using modern neural networks, trained with stochastic gradient descent. There exist multiple loss functions today, some claiming to be perceptual. Researchers at NVIDIA recently published a proposal of such a metric called FLIP. LÄS MER

  5. 4. Investigating the Adaptive Loop Filter in Next Generation Video Coding

    Master-uppsats, KTH/Skolan för elektro- och systemteknik (EES)

    Författare :Alfonso De La Rocha Gomes-Arevalillo; [2017]
    Nyckelord :Joint Exploration Model; JEM; Adaptive Loop Filter; variance-based adaptive quantization; video compression; video coding standards;

    Sammanfattning : Current trends on video technologies and services are demanding higher bit rates, highervideo resolutions and better video qualities. This issue results in the need of a new generationof video coding techniques to increase the quality and compression rates of previous standards. LÄS MER
