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

    Author : Zulfiqar Hasan Khan; [2012]
    Keywords : 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;

    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. 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; John Folkesson; Joydeep Biswas; [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

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

    University dissertation from Stockholm : KTH Royal Institute of Technology

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

    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 marking in the signed modality Verbal and nominal strategies in Swedish Sign Language and other sign languages

    University dissertation from Stockholm : Department of Linguistics, Stockholm University

    Author : Carl Börstell; Maria Koptjevskaja Tamm; Irit Meir; Roland Pfau; [2017]
    Keywords : HUMANIORA; HUMANITIES; sign language; object marking; differential object marking; argument structure; transitivity; valency; directionality; handshape; pronoun; perspective; Swedish Sign Language; Al-Sayyid Bedouin Sign Language; Israeli Sign Language; Linguistics; lingvistik;

    Abstract : In this dissertation, I investigate various aspects of object marking and how these manifest themselves in the signed modality. The main focus is on Swedish Sign Language (SSL), the national sign language of Sweden, which is the topic of investigation in all five studies. READ MORE
