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

   University essay from Stockholms universitet/Institutionen för data- och systemvetenskap

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

   Abstract : 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. READ MORE

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

   University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

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

   Abstract : 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. READ MORE

4. 3. Enabling Hybrid Real Time and Retrospectively Gated Imaging in a Numerical Phantom

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Sara Mineur; [2023]
   Keywords : Cardiovascular Magnetic resonance Imaging CMR ; Sector Wise Golden-Angle SWIG ;

   Abstract : Sector-Wise Golden Angle (SWIG) is a novel approach that was developed to address the limitations associated with Golden Angle radial imaging, commonly used for high temporal resolution flow measurements. Golden angle radial imaging is a time-efficient method that effectively reduces motion sensitivity. READ MORE

5. 4. Analyzing the Influence of Synthetic andAugmented Data on Segmentation Model

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Alex Peschel; [2023]
   Keywords : Artificial Intelligence; Microorganisms; Segmentation; Synthesizing; Augmentation;

   Abstract : The field of Artificial Intelligence (AI) has experienced unprecedented growth in recent years, thanks to the numerous applications related to speech recognition, natural language processing, and computer vision. However, one of the challenges facing AI is the requirement for large amounts of energy, time, and data to be effective and accurate. READ MORE

6. 5. ISAR Imaging Enhancement Without High-Resolution Ground Truth

   University essay from Linköpings universitet/Datorseende

   Author : Moltas Enåkander; [2023]
   Keywords : SAR; SAR Imaging; ISAR; ISAR Imaging; Machine learning; Convolutional neural network; CNN; neural network; Super resolution; Unsupervised learning;

   Abstract : In synthetic aperture radar (SAR) and inverse synthetic aperture radar (ISAR), an imaging radar emits electromagnetic waves of varying frequencies towards a target and the backscattered waves are collected. By either moving the radar antenna or rotating the target and combining the collected waves, a much longer synthetic aperture can be created. READ MORE
