  3. 3. Cluster-based Sample Selection for Document Image Binarization

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Amandus Krantz; [2019]
    Nyckelord :document image binarization; sample selection; neural networks; computer vision;

    Sammanfattning : The current state-of-the-art, in terms of performance, for solving document image binarization is training artificial neural networks on pre-labelled ground truth data. As such, it faces the same issues as other, more conventional, classification problems; requiring a large amount of training data. LÄS MER
