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

    University dissertation from Chalmers University of Technology

    Author : Zulfiqar H. Khan; Chalmers tekniska högskola.; Chalmers University of Technology.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bildanalys; Image analysis; Signalbehandling; Signal processing; Visual object tracking; anisotropic mean shift; particle filters; Bayesian tracking; consensus point feature correspondences; online learning of reference object; Riemannian manifold; covariance tracking; Gabor features; Grassmann manifold.;

    Abstract : 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. READ MORE

    Abstract : This thesis addresses a challenging problem: “how to let the visually impaired ‘see’ others emotions”. We, human beings, are heavily dependent on facial expressions to express ourselves. A smile shows that the person you are talking to is pleased, amused, relieved etc. READ MORE

  3. 3. Learning Object Properties From Manipulation for Manipulation

    University dissertation from US-AB : KTH Royal Institute of Technology

    Author : Püren Güler; KTH.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotics; manipulation; object properties; simulation; machine learning; object tracking; active exploration; sensory integration; Datalogi; Computer Science;

    Abstract : The world contains objects with various properties - rigid, granular, liquid, elastic or plastic. As humans, while interacting with the objects, we plan our manipulation by considering their properties. For instance, while holding a rigid object such as a brick, we adapt our grasp based on its centre of mass not to drop it. READ MORE

  4. 4. Visual Object Tracking and Classification Using Multiple Sensor Measurements

    University dissertation from Chalmers University of Technology

    Author : Yixiao Yun; Chalmers tekniska högskola.; Chalmers University of Technology.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Visual object tracking; visual pattern classification; multiple sensor measurement; sensor fusion; multiple view geometry; Riemannian manifold; boosting;

    Abstract : Multiple sensor measurement has gained in popularity for computer vision tasks such as visual object tracking and visual pattern classification. The main idea is that multiple sensors may provide rich and redundant information, due to wide spatial or frequency coverage of the scene, which is advantageous over single sensor measurement in learning object model/feature and inferring target state/attribute in complex scenarios.

  5. 5. Object Instance Detection and Dynamics Modeling in a Long-Term Mobile Robot Context

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Nils Bore; KTH.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotics; long-term; mapping; tracking; unsupervised learning; estimation; object modeling; Datalogi; Computer Science;

    Abstract : In the last years, simple service robots such as autonomous vacuum cleaners and lawn mowers have become commercially available and increasingly common. The next generation of service robots should perform more advanced tasks, such as to clean up objects. READ MORE
