  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. Virtual Staining of Blood Cells using Point Light Source Illumination and Deep Learning

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Joel Wulff; [2022]
    Nyckelord :Deep learning; virtual staining; blood; cells; GANs; Generative adversarial networks; CNNs; convolutional neural networks; ESRGAN; Unet; digital microscopy; Mathematics and Statistics;

    Sammanfattning : Blood tests are an important part of modern medicine, and are essentially always stained using chemical colorization methods before analysis by computational or manual methods. The staining process allows different parts of blood cells to be discerned that would be unnoticeable in unstained blood. LÄS MER

  4. 3. Fönstersättningars påverkan på dagsljuset i bostadsrum

    M1-uppsats, KTH/Byggvetenskap

    Författare :Charlotte Hejdenberg; Malin Brattström; [2015]
    Nyckelord :Bostäder; fönster; dagsljus; belysningsstyrka; dagsljusfaktor; Velux Visualizer;

    Sammanfattning : Dagsljuset i ett rum förmedlas via fönster. Fönsterutformningen har i sin tur en avsevärd effekt på rumsupplevelsen. Mängden litteratur som behandlar fönstrets historiska utveckling är stor. LÄS MER

  5. 4. Efficient Simulation and Rendering of Sub-surface Scattering

    Master-uppsats, Medie- och Informationsteknik; Tekniska högskolan

    Författare :Apostolia Tsirikoglou; [2013]
    Nyckelord :subsurface scattering; SSS; translucent materials; BSSRDF; shader; V-Ray; Maya; better dipole; quantized-diffusion;

    Sammanfattning : In this thesis, a new improved V-Ray subsurface scattering shader based on the improved diffusion theory is proposed. The new shader supports the better dipole and the quantized diffusion reflectance model for layered translucent materials. LÄS MER

  7. 5. An Illumination Model for Realistic Rendering of Snow Surfaces

    Master-uppsats, Institutionen för informationsteknologi

    Författare :Fei Liu; [2010]
    Nyckelord :;

    Sammanfattning : In this thesis work, several prominent visual effects of a snow surface under a strong light source, for instance, the sun, have been identified and modeled, which includes glittering, micro shadows and regional translucency due to subsurface light scattering. The glittering effect was implemented using blooming technique which makes candidate pixels’ colours bleed into their neighbours. LÄS MER
