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

    Author : Keren Fu; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

    Author : Keren Fu; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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.

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

    Author : Bastiaan Brouwer; Per Gardeström; Karin Krupinska; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis; darkness; light; photosynthesis; phytochrome; shade; senescence;

    Abstract : 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. READ MORE

  6. 4. On hydroxyapatite modified peek implants for bone applications

    Author : Pär Johansson; Malmö högskola; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dental Implants; Dentala implantat;

    Abstract : 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. READ MORE

  7. 5. Alternative splicing of interleukin-7

    Author : Nalini Kumar Vudattu; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : 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. READ MORE
