  1. 1. Texture based duplex-board layer segmentation

    Författare :Arash Fayyazi; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : A serial scanning electron microscopy images of paper was obtained by a slicing procedure The slicing procedure leads to misregistrations that have to be corrected. Two methods for registration of consecutive images are presented here.Duplex-board is used mainly for packaging liquids. It has a triple layer structure. LÄS MER
