  2. 1. Spatial Vision in Bees : Behavioural investigation of spatial resolution and contrast sensitivity

    Author : Aravin Chakravarthi; Funktionell zoologi; []
    Keywords : Insect vision; Honeybees; Bumblebees; Spatial resolution; Contrast sensitivity; Motion detection; Object discrimination;

    Abstract : Bees use multiple sensory modalities to perform day-to-day tasks. Light allows them to perceive objects and the general features of their surroundings, enabling them to find food and to navigate safely across the landscape. READ MORE

  4. 2. Forest planning utilizing high spatial resolution data

    Author : Pär Wilhelmsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : This thesis presents planning approaches adapted for high spatial resolution data from remote sensing and evaluate whether such approaches can enhance the provision of ecosystem services from forests. The presented methods are compared with conventional, stand-level methods. READ MORE

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

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

    Abstract : 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.

  6. 4. Urban Land-cover Mapping with High-resolution Spaceborne SAR Data

    Author : Hongtao Hu; Yifang Ban; Johan Fransson; KTH; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; High-resolution; RADARSAT-1 SAR; RADARSAT-2 SAR; Urban Land Cover; Object-based Classification; Neural Network; Support Vector Machines.; Remote sensing; Fjärranalys;

    Abstract : Urban areas around the world are changing constantly and therefore it is necessary to update urban land cover maps regularly. Remote sensing techniques have been used to monitor changes and update land-use/land-cover information in urban areas for decades. Optical imaging systems have received most of the attention in urban studies. READ MORE

  7. 5. Spatial vision in diverse invertebrates

    Author : John Kirwan; Funktionell zoologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; vision; visual ecology; invertebrates; spatial resolution; behaviour;

    Abstract : Light-detection provides incomparabaly rapid information at a range of time scales and, consequently, directional photoreception is found in almost every major metazoan clade. Conversely, a much smaller cohort have evolved sophisticated high resolution vision, which facillitates complex tasks via the detection of fast or small objects,. READ MORE
