    Sammanfattning : Unmanned Aerial Vehicles (UAVs) provide a flexible method for acquiring high-resolution imagery with relative simple operation and cost-effectiveness. This technology emerged 30 years ago and it is widely used by commercial, scientific, and military communities due to its versatility. However, new technology brings new challenges. LÄS MER

  5. 4. Accurate BRDF Modelling for Wide Angle Scattering

    Master-uppsats, Medie- och Informationsteknik; Tekniska högskolan

    Författare :Tanaboon Tongbuasirilai; [2013]
    Nyckelord :brdf; microfacet; wide-angle scattering;

    Sammanfattning : In this thesis, a modified BRDF model for wide-angle scattering is presented. The proposed model is developed from empirical observations of several BRDF models. The model is an extention of the classical microfacet models. LÄS MER
