  1. 1. Extensions and Applications of Affine Shape

    Författare :Rikard Berthilsson; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Systems engineering; Matematik; Mathematics; density of shape; maximum likelihood; matching constraint; surface; curve; handwriting; recognition; affine shape; reconstruction; computer technology; Data- och systemvetenskap;

    Sammanfattning : A central problem in computer vision is to reconstruct the three-dimensional structure of a scene from a set of two-dimensional images. Traditionally this is done by extracting a set of characteristic points in the scene and to compute a reconstruction of these points. LÄS MER

  3. 2. Automatic Shape Modelling with Applications in Medical Imaging

    Författare :Anders Ericsson; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; heart-infarction; lung-embolie; Parkinson; DaTSCAN; SPECT; SCINT; affine shape; MDL; automatic shape models; Deformable models; active shape; Mathematics; Matematik;

    Sammanfattning : This thesis consists of two parts. The first part is devoted to automatic shape analysis and the second part is devoted to decision support systems in medical imaging. Shape models are widely used in segmentation and shape analysis. The thesis begins with a review of deformable models and the preliminaries of shape modelling. LÄS MER

  4. 3. Robust Visual Object Tracking mean shift, particle filters and point features

    Författare :Zulfiqar Hasan Khan; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PF; MSEPF; mean shift; visual object tracking; RANSAC; SIFT; SURF;

    Sammanfattning : Visual object tracking has been identified as a promising technique for many computer vision applications like surveillance, flight navigation, video compression and driver assistance. The main idea is to find the state ofthe object and how it changes over time, in recursive video frames. LÄS MER

  5. 4. Methods for Visually Guided Robotic Systems : Matching, Tracking and Servoing

    Författare :Fredrik Larsson; Michael Felsberg; Per-Erik Forssén; Josef Bigün; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This thesis deals with three topics; Bayesian tracking, shape matching and visual servoing. These topics are bound together by the goal of visual control of robotic systems. The work leading to this thesis was conducted within two European projects, COSPAL and DIPLECS, both with the stated goal of developing artificial cognitive systems. LÄS MER

  7. 5. Dynamics and limits in algebraic combinatorics

    Författare :Samu Potka; Svante Linusson; Victor Reiner; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Sammanfattning : This thesis consists of the following six articles.Properties of the Edelman-Greene bijection. Edelman and Greene constructed a correspondence between reduced words of the reverse permutation and standard Young tableaux. LÄS MER
