  1. 1. Virtual H&E Staining Using PLS Microscopy and Neural Networks

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Sally Vizins; Hanna Råhnängen; [2024]
    Nyckelord :Deep learning; Virtual staining; Skin tissue; Hematoxylin Eosin; H E; Pathology; Carcinoma; Point light source illumination; Neural Networks; GANs; Generative adversarial networks; CNNs; Convolutional neural networks; Relativistic generative adversarial network; Unet; Digital microscopy; Attention-Unet; Dense-Unet; Mathematics and Statistics;

    Sammanfattning : Histopathological examination, crucial in diagnosing diseases such as cancer, traditionally relies on time- and resource-consuming, poorly standardized chemical staining for tissue visualization. This thesis presents a novel digital alternative using generative neural networks and a point light source (PLS) microscope to transform unstained skin tissue images into their stained counterparts.

  3. 2. Improving bright-field images for tracking particles with Defocustracker

    Kandidat-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Carl Lundin; [2022]
    Nyckelord :Defocustracker; GDPT; particle tracking; bright-field; acoustophoresis; Laplacian of Gaussian; Technology and Engineering;

    Sammanfattning : Acoustophoresis is a cell separation technology where particles or cells are suspended in a fluid container and subject to acoustic standing waves. The standing waves exerts an acoustic radiation force on the particles, pushing them towards the nodal plane. LÄS MER

  4. 3. Contrastive Multimodal Image Representations for Deformable Image Registration

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Love Nordling; [2022]
    Nyckelord :;

    Sammanfattning : Image registration is the process of finding correspondences between images of the same or of similar scenes. Multimodal image registration is the specific case where the images are captured with different imaging systems. LÄS MER

  5. 4. Mapping of Chromosome Dynamics over the Bacterial Cell Cycle

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för cell- och molekylärbiologi

    Författare :Konrad Gras; [2018]
    Nyckelord :;

    Sammanfattning : The replication of DNA, its compaction and segregation in dividingcells are challenges which all organisms are faced with. Ensuringthat these processes occur without error is essential for thesurvival of the organism. LÄS MER

  7. 5. Neural network based fault detection on painted surface

    Master-uppsats, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Midhumol Augustian; [2017]
    Nyckelord :Artificial neural network; machine vision; paint fault detection;

    Sammanfattning : Machine vision systems combined with classification algorithms are being increasingly used for different applications in the age of automation. One such application would be the quality control of the painted automobile parts. LÄS MER
