    Abstract : 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. READ MORE

  5. 4. Accurate BRDF Modelling for Wide Angle Scattering

    University essay from Medie- och Informationsteknik; Tekniska högskolan

    Author : Tanaboon Tongbuasirilai; [2013]
    Keywords : brdf; microfacet; wide-angle scattering;

    Abstract : 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. READ MORE

  6. 5. Study of scattered light generated by silicon carbide mirrors
