  1. 1. Industrial 3D Anomaly Detection and Localization Using Unsupervised Machine Learning

    University essay from Linköpings universitet/Datorseende

    Author : Kevin Bärudde; Marcus Gandal; [2023]
    Keywords : Machine Learning; 3D Anomaly Detection; Feature Extraction; Manufacturing; Computer Vision; Vision Transformer; PointNet;

    Abstract : Detecting defects in industrially manufactured products is crucial to ensure their safety and quality. This process can be both expensive and error-prone if done manually, making automated solutions desirable. READ MORE

  2. 2. Automatic Detection of Common Signal Quality Issues in MRI Data using Deep Neural Networks

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : Erika Ax; Elin Djerf; [2023]
    Keywords : mr; magnetic resonance; machine learning; deep learning; anomaly detection; U-Net; autoencoder; 3D; classification; reconstruction; artefacts;

    Abstract : Magnetic resonance imaging (MRI) is a commonly used non-invasive imaging technique that provides high resolution images of soft tissue. One problem with MRI is that it is sensitive to signal quality issues. The issues can arise for various reasons, for example by metal located either inside or outside of the body. READ MORE

  3. 3. Coronary Artery Plaque Segmentation with CTA Images Based on Deep Learning

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

    Author : Zhang Shuli; [2022]
    Keywords : Coronary Plaque Segmentation; CTA image; nnU-Net; FCDD; Anomaly Detection; Koronarplacksegmentering; CTA-bild; nnU-Net; FCDD; Anomalidetektering;

    Abstract : Atherosclerotic plaque is currently the leading cause of coronary artery disease (CAD). With the help of CT images, we can identify the size and type of plaque, which can help doctors make a correct diagnosis. To do this, we need to segment coronary plaques from CT images. READ MORE

  4. 4. Learning from 3D generated synthetic data for unsupervised anomaly detection

    University essay from Uppsala universitet/Avdelningen för visuell information och interaktion

    Author : Hampus Fröjdholm; [2021]
    Keywords : machine learning; synthetic data; anomaly detection; physically based rendering; maskininlärning; syntetisk data; anomalidetektion;

    Abstract : Modern machine learning methods, utilising neural networks, require a lot of training data. Data gathering and preparation has thus become a major bottleneck in the machine learning pipeline and researchers often use large public datasets to conduct their research (such as the ImageNet [1] or MNIST [2] datasets).
