  1. 1. Study of radiometric variations in Unmanned Aerial Vehicle remote sensing imagery for vegetation mapping

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Maria Ximena Tagle Casapia; [2017]
    Nyckelord :vegetation mapping; UAV; radiometric correction; vegetation indices; GEM; Earth and Environmental Sciences;

    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

  2. 2. Accurate BRDF Modelling for Wide Angle Scattering

    Master-uppsats, Linköpings universitet/Medie- och InformationsteknikLinköpings universitet/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

  3. 3. What is creativity - a study of the usage and interpretation at an advertising agency

    M1-uppsats, Linköpings universitet/Medie- och InformationsteknikLinköpings universitet/Tekniska högskolan; Linköpings universitet/Medie- och InformationsteknikLinköpings universitet/Tekniska högskolan

    Författare :Louise Boström; Elin Hoffmeister; [2013]
    Nyckelord :Kreativitet; kreativ; definition; begrepp; creativity; creative;

    Sammanfattning : With the development of modern GPUs, the computational power they provide have become more accessible and versatile. This has fueled the development of interactive visualization techniques and among them volumetric visualization. LÄS MER

  4. 4. Study of scattered light generated by silicon carbide mirrors

    Master-uppsats, KTH/Rymd- och plasmafysik

    Författare :Guillaume Langin; [2012]
    Nyckelord :;

    Sammanfattning : Silicon carbide (SiC) shows promise as an increasingly widespread material for aerospace mirror systems. It has already been successfully used in recent space programs, with and without Chemical Vapor Deposition (CVD). LÄS MER

  5. 5. Pre-computed surface radiance transfer

    Magister-uppsats, Linköpings universitet/Linköpings universitet/Institutionen för teknik och naturvetenskapTekniska högskolan

    Författare :Jos Timanta Tarigan; [2011]
    Nyckelord :;

    Sammanfattning : Rendering a complex global illumination scene requires an extensive computational resource. It is hard to achieve a real time rendering of a complex object using explicit 3D information. To tackle this obstacle, many techniques have been introduced to close the gap between complex 3D scene and real time rendering. LÄS MER
