  1. 1. Interest Curves : Concept, Evaluation, Implementation and Applications

    Författare :Bo Li; Ulrik Söderström; Haibo Li; Björn Kruse; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; scale-invariance; edge; corner; curve; line; matching; object detection; signalbehandling; Signal Processing;

    Sammanfattning : Image features play important roles in a wide range of computer vision applications, such as image registration, 3D reconstruction, object detection and video understanding. These image features include edges, contours, corners, regions, lines, curves, interest points, etc. LÄS MER

  3. 2. Feature extraction based on a tensor image description

    Författare :Carl-Fredrik Westin; Linköpings universitet; []
    Nyckelord :Image analysis; Representation; Tensor; Hough transform; Möbius strip; Corner detection; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Feature extraction from a tensor based local image representation introduced by Knutsson in [37] is discussed. The tensor representation keeps statements of structure, certainty of statement and energy separate. LÄS MER

  4. 3. Multiscale Curvature Detection in Computer Vision

    Författare :Björn Johansson; Gösta Granlund; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This thesis presents a new method for detection of complex curvatures such as corners, circles, and star patterns. The method is based on a second degree local polynomial model applied to a local orientation description in double angle representation. LÄS MER

  5. 4. Tools to Compile Dataflow Programs for Manycores

    Författare :Essayas Gebrewahid; Zain Ul-Abdin; Veronica Gaspes; Bertil Svensson; Marco Mattavelli; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The arrival of manycore systems enforces new approaches for developing applications in order to exploit the available hardware resources. Developing applications for manycores requires programmers to partition the application into subtasks, consider the dependence between the subtasks, understand the underlying hardware and select an appropriate programming model. LÄS MER

  7. 5. Compiling Concurrent Programs for Manycores

    Författare :Essayas Gebrewahid; Bertil Svensson; Veronica Gaspes; Zain Ul-Abdin; Johan Eker; Högskolan i Halmstad; []
