  1. 1. AI-based image generation: The impact of fine-tuning on fake image detection

    Kandidat-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

    Författare :Nick Hagström; Anders Rydberg; [2024]
    Nyckelord :Fake image detection; LoRA; DreamBooth; Stable Diffusion; Image generation;

    Sammanfattning : Machine learning-based image generation models such as Stable Diffusion are now capable of generating synthetic images that are difficult to distinguish from real images, which gives rise to a number of legal and ethical concerns. As a potential measure of mitigation, it is possible to train neural networks to detect the digital artifacts present in the images synthesized by many generative models. LÄS MER

  3. 2. Particle Detection in Bone Marrow Using CNNs and Transformer Networks

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Anna Källén; Marcus Williams; [2023]
    Nyckelord :Bone Marrow; Dark Field Microscopy; Fourier Ptychography; Machine Learning; Convolutional Neural Networks; Transformer Networks; Quantisation; Technology and Engineering;

    Sammanfattning : The critical role of hematological stem cells, concentrated in bone marrow, in disease diagnosis makes the detection of these cells an imperative task. The current process, however, is slow and heavily reliant on expert interpretation, underscoring the need for automation. LÄS MER

  5. 4. Cooperative edge deepfake detection

    Kandidat-uppsats, Jönköping University/JTH, Avdelningen för datateknik och informatik

    Författare :Enis Hasanaj; Albert Aveler; William Söder; [2021]
    Nyckelord :Machine learning; deepfake; artificial intelligence; ensemble; convolutional neural networks; edge; YOLOv2;

    Sammanfattning : Deepfakes are an emerging problem in social media and for celebrities and political profiles, it can be devastating to their reputation if the technology ends up in the wrong hands. Creating deepfakes is becoming increasingly easy. LÄS MER

  7. 5. Data Augmentation for Safe 3D Object Detection for Autonomous Volvo Construction Vehicles

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Xun Zhao; [2021]
    Nyckelord :Point Cloud; Data Augmentation; Data Annotation; 3D Object Detection; Generative Adversarial Network; Computer Vision.;

    Sammanfattning : Point cloud data can express the 3D features of objects, and is an important data type in the field of 3D object detection. Since point cloud data is more difficult to collect than image data and the scale of existing datasets is smaller, point cloud data augmentation is introduced to allow more features to be discovered on existing data.
