  1. 21. On Medical Image Segmentation With Noisy Labels

    Författare :Marcus Nordström; Henrik Hult; Atsuto Maki; Fredrik Kahl; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Medical image segmentation; image segmentation; machine learning; supervised learning; label noise; Sörensen-Dice coefficient; soft-Dice; Medicinsk bildsegmentering; bildsegmentering; maskininlärning; övervakat lärande; annoteringsbrus; Sörensen-Dice koefficienten; soft-Dice; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics; Mathematical Statistics; Matematisk statistik;

    Sammanfattning : It is well known that data sets used for training and testing automatic medical image segmentation methods often contain a lot of label noise. Such noise affects the performance of the methods and has been subject to a lot of research. LÄS MER

    Sammanfattning : The aim of this thesis is to contribute knowledge about children’s image-vision, image-thinking and image- and filmmaking in preschool, through a collaboration with children and digital film technology, and about Gilles Deleuze’s film philosophy (1989) as well as digital videography and the methodology created in the research process. The empirical production was carried out as a digital decentralized videography, according to Pink et al. LÄS MER

  5. 24. Graph-based Methods for Interactive Image Segmentation

    Författare :Filip Malmberg; Ingela Nyström; Ewert Bengtsson; Jayaram K. Udupa; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Digital image analysis; Interactive image segmentation; Fuzzy image segmentation; Image foresting transform; Graph labeling; Graph cuts; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : The subject of digital image analysis deals with extracting relevant information from image data, stored in digital form in a computer. A fundamental problem in image analysis is image segmentation, i.e., the identification and separation of relevant objects and structures in an image. LÄS MER

    Sammanfattning : For the Armenian-Russian mathematician, theologian and art-theoretician Pavel Florensky (1882–1937), the so-called reverse perspective of the Byzantine cult-image (in Greek: eikon) functioned not only as a phenomenon within painting, but also as an expression of a world-view that should ultimately define a cultural distinction between Russia and Europe. Florensky argued in various ways that the Russian-Orthodox reverse perspective represents ethical and aesthetical values that are superior to the Western linear perspective. LÄS MER
