  2. 16. 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. 17. The Texture-Transform : An Operator for Texture Detection and Discrimination

    Author : Alireza Tavakoli Targhi; Jan-Olof Eklundh; Arnold Smeulders; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datalogi;

    Abstract : In this thesis we present contributions related to texture detection and discrimination to be used for analyzing real world images. Many computer vision applications can benefit from a fast and low dimensional texture descriptor. READ MORE

  5. 18. Translational Research of Mendelian Disorders : Applications of Cutting-Edge Sequencing Techniques and Molecular Tools

    Author : Sanna Gudmundsson; Marie-Louise Bondeson; Maria Wilbe; Niklas Dahl; Joris Veltman; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; translational research; Mendelian disorders; intellectual disability; sequencing technologies;

    Abstract : Up to 8% of all live-born children are affected with a congenital disorder. Some are Mendelian disorders of known etiology, but many are of undetermined genetic cause and mechanism, limiting diagnosis and treatment. READ MORE

  6. 19. Active Health Monitoring of Aerospace Composite Structures by Embedded Piezoceramic Transducers

    Author : Christophe Paget; KTH; []
    Keywords : embedded; piezoceramic; piezoelectric; transducer; composite; structural; integrity; health monitoring; damage detection; Lamb waves; wavelets; normal-mode expansion; FE-method; SLMT;

    Abstract : The objectives of the thesis work were to study theinteraction between embedded piezoceramic transducers andcomposite structures as well as determine techniques tosimplify the Lamb waves analysis. Firstly, this studyconsidered the design of the embedded piezoceramic transducers. READ MORE

  7. 20. Binding Three Kinds of Vision

    Author : Leo Poom; Myron Braunstein; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Attribute-invariance; binding; contours; edge linking; gestalt-laws; illusory contour; lateral interactions; neuronal mechanisms; tilt effect; vision; Psykologi; Psychology; Psykologi; Psychology; psykologi;

    Abstract : Pictorial cues, together with motion and stereoscopic depth fields, can be used for perception and constitute ‘three kinds’ of vision. Edges in images are important features and can be created in either of these attributes. READ MORE
