  1. 1. Anomaly Detection with Machine Learning using CLIP in a Video Surveillance Context

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Christoffer Gärdin; [2023]
    Nyckelord :Datorseende; maskininlärning; CLIP; anomalidetektion; videoövervakning;

    Sammanfattning : This thesis explores the application of Contrastive Language-Image Pre-Training (CLIP), a vision-language model, in an automated video surveillance system for anomaly detection. The ability of CLIP to perform zero-shot learning, coupled with its robustness against minor image alterations due to its lack of reliance on pixel-level image analysis, makes it a suitable candidate for this application.

  3. 2. Weakly-Supervised Diagnosis with Attention Models

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

    Författare :Zaoshi Ying; [2022]
    Nyckelord :;

    Sammanfattning : With the rapid development of data-driven solutions, a high-quality dataset with fine labels can well tackle fault diagnosis problems. However, in industry assets, the quality of the dataset depends much on the experience and capability of the annotation engineer. Therefore, strong labels are usually hard and expensive to acquire.

  4. 3. Classification of brain tumors in weakly annotated histopathology images with deep learning

    Master-uppsats, Linköpings universitet/Statistik och maskininlärning

    Författare :Dávid Hrabovszki; [2021]
    Nyckelord :medical imaging; deep learning; glioblastoma; tcga; brain tumor; weakly supervised; histopathology; digital pathology; histology;

    Sammanfattning : Brain and nervous system tumors were responsible for around 250,000 deaths in 2020 worldwide. Correctly identifying different tumors is very important, because treatment options largely depend on the diagnosis. LÄS MER

  5. 4. Prioritization of Informative Regions in PET Scans for Classification of Alzheimer's Disease

    Uppsats för yrkesexamina på avancerad nivå, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Fredrik Mårtensson; Erik Westberg; [2021]
    Nyckelord :;

    Sammanfattning : Alzheimer’s Disease (AD) is a widespread neurodegenerative disease. The disease causes brain atrophy, resulting in memory loss, decreased cognitive ability, and eventually death. There is currently no cure for the disease, but treatment may delay the onset. Therefore, it is crucial to detect the disease at an early stage. LÄS MER

  7. 5. Multi-site Organ Detection in CT Images using Deep Learning

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

    Författare :Gustaf Jacobzon; [2020]
    Nyckelord :Organ Detection; Organs-at-risk; 3D Object Detection; Segmentation; Deep Learning; Machine Learning; Weakly-supervised Learning; YOLOv3; 3D U-Net;

    Sammanfattning : When optimizing a controlled dose in radiotherapy, high resolution spatial information about healthy organs in close proximity to the malignant cells are necessary in order to mitigate dispersion into these organs-at-risk. This information can be provided by deep volumetric segmentation networks, such as 3D U-Net. LÄS MER
