  1. 1. Acoustic Sound Source Localisation and Tracking : in Indoor Environments

    Författare :Anders Johansson; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Room acoustics; Speaker localisation; Tracking; State-space filter; Sequential Monte Carlo method; Particle filter;

    Sammanfattning : With advances in micro-electronic complexity and fabrication, sophisticated algorithms for source localisation and tracking can now be deployed in cost sensitive appliances for both consumer and commercial markets. As a result, such algorithms are becoming ubiquitous elements of contemporary communication, robotics and surveillance systems. LÄS MER

  3. 2. Segmentation and tracking of cells and particles in time-lapse microscopy

    Författare :Klas E. G. Magnusson; Joakim Jaldén; Dirk Padfield; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cell tracking; Particle tracking; Multiple target tracking; Image segmentation; Image processing; Computer vision; Open source software; Time-lapse microscopy; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : In biology, many different kinds of microscopy are used to study cells. There are many different kinds of transmission microscopy, where light is passed through the cells, that can be used without staining or other treatments that can harm the cells. LÄS MER

  4. 3. Detection and Tracking in Thermal Infrared Imagery

    Författare :Amanda Berg; Michael Felsberg; Jörgen Ahlberg; Thomas B. Moeslund; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; thermal; infrared; detection; tracking;

    Sammanfattning : Thermal cameras have historically been of interest mainly for military applications. Increasing image quality and resolution combined with decreasing price and size during recent years have, however, opened up new application areas. They are now widely used for civilian applications, e.g. LÄS MER

  5. 4. Stochastic Modeling for Video Object Tracking and Online Learning: manifolds and particle filters

    Författare :Zulfiqar Hasan Khan; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; anisotropic mean shift; online learning of reference object; covariance tracking; consensus point feature correspondences; Bayesian tracking; Gabor features; Visual object tracking; Grassmann manifold.; Riemannian manifold; particle filters;

    Sammanfattning : Classical visual object tracking techniques provide effective methods when parameters of the underlying process lie in a vector space. However, various parameter spaces commonly occurring in visual tracking violate this assumption. LÄS MER

  7. 5. Recursive Bayesian Estimation : Navigation and Tracking Applications

    Författare :Niclas Bergman; Fredrik Gustafsson; Lennart Ljung; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Target tracking; Autonomous aircraft navigation; Terrain navigation;

    Sammanfattning : Recursive estimation deals with the problem of extracting information about parameters, or states, of a dynamical system in real time, given noisy measurements of the system output. Recursive estimation plays a central role in many applications of signal processing, system identification and automatic control. LÄS MER
