  4. 23. Cell Identification from Microscopy Images using Deep Learning on Automatically Labeled Data

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Fredrik Salomon-Sörensen; [2023]
    Nyckelord :Deep Learning; Cell Identification; Image Segmentation; Nuclei Segmentation; Convolutional Neural Networks; UNet; Image Analysis; Microscopy; Noisy Labels; Phase-Contrast; Automatic Labeling; Technology and Engineering;

    Sammanfattning : In biology, cell counting provides a fundamental metric for live-cell experiments. Unfortunately, most researchers are constrained to using tedious and invasive methods for counting cells. Automatic identification of cells in microscopy images would therefore be a valuable tool for such researchers. LÄS MER

  5. 24. China's elderly trapped in the digital age : A qualitative study on the elderly in a fourth-tier city

    Magister-uppsats, Uppsala universitet/Institutionen för informatik och media

    Författare :Siyu Xu; [2023]
    Nyckelord :Chinese elderly; ICTs; digital divide;

    Sammanfattning : China is moving into an aging society, and the quality of life of the elderly has become a topic of public concern. With the development of ICT technology, China’s digital level is increasing, and there is a digital literacy gap between the young and the elderly, and the intergenerational digital divide is widening.
