  4. 3. Integral Video Coding

    Master-uppsats, KTH/Kommunikationsteori

    Författare :Fan Yang; [2014]
    Nyckelord :Integral Imaging; HEVC; MV-HEVC; Multi-view video coding; Lytro;

    Sammanfattning : In recent years, 3D camera products and prototypes based on Integral imaging (II) technique have gradually emerged and gained broad attention. II is a method that spatially samples the natural light (light field) of a scene, usually using a microlens array or a camera array and records the light field using a high resolution 2D image sensor.
