  1. 1. The high dynamic range imaging pipeline : Tone-mapping, distribution, and single-exposure reconstruction

    Författare :Gabriel Eilertsen; Jonas Unger; Rafał Mantiuk.; Anders Ynnerman; Erik Reinhard; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; high dynamic range imaging; tone-mapping; video tone-mapping; HDR video encoding; HDR image reconstruction; inverse tone-mapping; machine learning; deep learning;

    Sammanfattning : Techniques for high dynamic range (HDR) imaging make it possible to capture and store an increased range of luminances and colors as compared to what can be achieved with a conventional camera. This high amount of image information can be used in a wide range of applications, such as HDR displays, image-based lighting, tone-mapping, computer vision, and post-processing operations. LÄS MER

  3. 2. Towards Joint Super-Resolution and High Dynamic Range Image Reconstruction

    Författare :Tomas Bengtsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Super-resolution; Dynamic range; Human visual system; Inverse problem; Image reconstruction; Spatial alignment; Photometric alignment; Digital camera system;

    Sammanfattning : The main objective for digital image- and video camera systems is to reproduce a real-world scene in such a way that a high visual quality is obtained. A crucial aspect in this regard is, naturally, the quality of the hardware components of the camera device. There are, however, always some undesired limitations imposed by the sensor of the camera.

  5. 4. Extending dynamic vegetation models to simulate range shifts

    Författare :Deborah Zani; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dynamic vegetation model; range shift; migration; paleovegetation;

    Sammanfattning : In response to rapid climate change and increasing human pressure, a wide variety of taxa have shifted their distribution in the past decades (range shift), with important consequences for ecosystem services and human health and economy. However, it is not yet clear whether most species will be able to track their favourable habitats or lag behind the climate signal (migration lag). LÄS MER
