  1. 1. Salient Region Detection Methods with Application to Traffic Sign Recognition from Street View Images

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Keren Fu; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; normalized cut; traffic sign recognition; saliency propagation; color distribution; continuous conditional random field; manifold; Salient region detection; adaptive graph edge weights; color contrast; geodesics;

    Sammanfattning : In the computer vision community, saliency detection refers to modeling the selective mechanism in human visual attentions. Outputs of saliency detection algorithms are called saliency maps, which represent conspicuousness levels of different scene areas. LÄS MER

  2. 2. Enhancement of Salient Image Regions for Visual Object Detection

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Keren Fu; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geodesic distance; graph spectral decomposition; video processing; visual attention; color contrast and distribution; propagation; salient region; figure-ground segmentation;

    Sammanfattning : Salient object/region detection aims at finding interesting regions in images and videos, since such regions contain important information and easily attract human attention. The detected regions can be further used for more complicated computer vision applications such as object detection and recognition, image compression, content-based image editing, and image retrieval.

  3. 3. Shedding Light on Shade- and Dark-Induced Leaf Senescence

    Detta är en avhandling från Umeå : KBC, Umeå University

    Författare :Bastiaan Brouwer; Umeå universitet.; Umeå universitet.; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis; darkness; light; photosynthesis; phytochrome; shade; senescence;

    Sammanfattning : Leaf senescence is the final stage of leaf development, during which the leaf relocates most of itsvaluable nutrients to developing or storing parts of the plant. As this process progresses, leaves losetheir green color and their capacity to perform photosynthesis. LÄS MER

  4. 4. Alternative splicing of interleukin-7

    Detta är en avhandling från Stockholm : Karolinska Institutet, Department of Microbiology, Tumor and Cell Biology

    Författare :Nalini Kumar Vudattu; Karolinska Institutet.; Karolinska Institutet.; [2009]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Alternative splicing of pre-mRNA is the primary source of creating proteome diversity in humans; it is therefore highly relevant to disease and therapy. Alternative splicing has been described for many cytokines and these splice variants appear to function as either agonists or as antagonists of the wildtype cytokine. LÄS MER

  5. 5. On hydroxyapatite modified peek implants for bone applications

    Detta är en avhandling från Malmö University, Department of Prosthetic dentistry

    Författare :Pär Johansson; Malmö University.; [2017]
    Nyckelord :ODONTOLOGY; ODONTOLOGI; Medicine; Dental Implants; Dentala implantat;

    Sammanfattning : People are living longer today than ever before, and the number of older adults will increase exponentially over the next coming years. However, that does not necessarily mean that they are living healthier. LÄS MER
