  1. 11. Incident Light Fields

    Författare :Jonas Unger; Anders Ynnerman; Reiner Lenz; Alan Chalmers; Linköpings universitet; []
    Nyckelord :Computer Graphics; Image Based Lighting; Photorealistic Rendering; Light Fields; High Dynamic Range Imaging; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Image based lighting, (IBL), is a computer graphics technique for creating photorealistic renderings of synthetic objects such that they can be placed into real world scenes. IBL has been widely recognized and is today used in commercial production pipelines. However, the current techniques only use illumination captured at a single point in space. LÄS MER

  3. 12. In Light of Ionic Materials : A short exploration of ionic materials for light-related applications

    Författare :Brando Adranno; Anja-Verena Mudring; Annegret Stark; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ionic materials; ionic liquids; mesophases; light-emission; electrochemical applications; materialkemi; Materials Chemistry;

    Sammanfattning : Ionic liquids (ILs) have been one of the most attractive classes of materials of the last decades. The reason behind this is their peculiar set of properties, which enable their possible application in several research fields. ILs are salts that exhibit a very low melting point, which has been arbitrarily defined to be below 100 °C. LÄS MER

  4. 13. Celestial Orientation in Dim Light

    Författare :Marie Dacke; Funktionell zoologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polarisation pattern; moon; polrised light detection; twilight; dim light; dung beetle; Zoologi; spider; vision; orientation; Zoology;

    Sammanfattning : The polarization pattern of skylight offers many animals a reference for visual compass orientation. In those cases when this optical compass is identified, the receptors involved are often confined to a small part of an eye built predominantly for other visual tasks. LÄS MER

  5. 14. Polymer light-emitting electrochemical cells : Utilizing doping for generation of light

    Författare :Piotr Matyba; Ludvig Edman; Qibing Pei; Umeå universitet; []
    Nyckelord :;

    Sammanfattning :     The current implementation of conjugated polymers (“conducting plastics”) in a wide range of devices promises to bring the vision of a new generation of flexible, efficient and low-cost applications to reality. Plastic lightemitting devices in the form of polymer light-emitting diodes (PLEDs) are projected to be particularly close to the market in applications such as large area and conformable illumination panels and high-performance thin displays.

  7. 15. Computational Light Field Photography : Depth Estimation, Demosaicing, and Super-Resolution

    Författare :Yongwei Li; Mårten Sjöström; Roger Olsson; Paolo Favaro; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Light field; computational photography; depth estimation; demosaicing; super-resolution;

    Sammanfattning : The transition of camera technology from film-based cameras to digital cameras has been witnessed in the past twenty years, along with impressive technological advances in processing massively digitized media content. Today, a new evolution emerged -- the migration from 2D content to immersive perception. LÄS MER
