  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. On Modelling Nonlinear Variation in Discrete Appearances of Objects

    Author : Felix Wehrmann; Ewert Bengtsson; Lennart Thurfjell; Fredrik Bergholm; Timothy Cootes; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bildanalys; image analysis; shape description; nonlinear modelling; manifold reconstruction; auto-associative neural network; Bildanalys; Image analysis; Bildanalys;

    Abstract : Mathematical models of classes of objects can significantly contribute to the analysis of digital images. A major problem in modelling is to establish suitable descriptions that cover not only a single object but also the variation that is usually present within a class of objects. READ MORE

  5. 3. Entropy and Speech

    Author : Mattias Nilsson; Bastian Kleijn; Sören Holdt Jensen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; speech representation; energy concentration; entropy estimation; manifolds; Acoustics; Akustik;

    Abstract : In this thesis, we study the representation of speech signals and the estimation of information-theoretical measures from observations containing features of the speech signal. The main body of the thesis consists of four research papers. Paper A presents a compact representation of the speech signal that facilitates perfect reconstruction. READ MORE

  6. 4. ForSyDe-Atom: Design of Heterogeneous Embedded Systems : Taming Complexity with Layers, Atoms and Patterns

    Author : George Ungureanu; Ingo Sander; Reinhard von Hanxleden; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; system design languages; modeling; simulation; synthesis; embedded systems; cyber-physical systems; domain specific languages; systemdesignspråk; modellering; simulering; syntes; inbyggda system; cyberfysiska system; domänspecifika språk; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : The design of embedded systems is inherently complex for two main reasons. Firstly, it entails the combined knowledge and results from a vast set of mature, well-established, yet separate disciplines, such as electrical engineering, computer science, mechanical engineering, etc. READ MORE
