  7. 30. Stochastic Modelling and Reconstruction of Random Shapes

    Författare :Finn Lindgren; Matematisk statistik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; operations research; Statistics; operationsanalys; Statistik; programmering; aktuariematematik; actuarial mathematics; programming;

    Sammanfattning : This thesis originates from the problem of reconstructing the three-dimensional shape of objects, when the only available data are two-dimensional images. The solution presented is based on stochastic models for random object shapes and measurements, in combination with practical surface representation and simulation methods. LÄS MER
