  1. 6. Electronic Labyrinths : An Archaeology of Videographic Cinema

    Författare :Jonathan Rozenkrantz; Trond Lundemo; Malin Wahlberg; Patricia Pisters; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; videographic cinema; video images in films; media archaeology; imaginary media; media imaginaries; live television drama; video therapy; video surveillance; video art; reality TV; mediated memories; media history; YouTube; retro; analogue nostalgia; filmvetenskap; Cinema Studies;

    Sammanfattning : This study scans six decades of film history in search for video images, the imaginaries within which they are framed, and (taking cues from the archaeological methods of Friedrich Kittler and Michel Foucault) their technical, historical, and institutional conditions of existence. The British experimental science fiction film Anti-Clock (Jane Arden and Jack Bond, 1979) revolves around a video device with the capacity to confront subjects with their own repressed memory images.

  3. 7. Live Mobile Video Interaction : Inventing and investigating technology, formats and applications

    Författare :Mudassar Ahmad Mughal; Oskar Juhlin; Gina Venolia; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; human computer interaction; liveness; live; ambient video; mobile webcasting; Computer and Systems Sciences; data- och systemvetenskap;

    Sammanfattning : The convergence of inexpensive video-enabled mobile phones, high-speed mobile data networks and ubiquitous sensing devices opens up a new design space called “live mobile video interaction”. It gives rise to a new genre of applications concerning live mobile video production, which can be seen as an instance of the said space. LÄS MER

  4. 8. Efficient multicast video streaming over heterogeneous networks

    Författare :Patrik Österberg; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; multicast; fairness; video; Computer science; Datavetenskap;

    Sammanfattning : The demand for real-time video streaming over Internet is ever growing. The aggregated bandwidth of the video flows can be substantial, which motivates the use of bandwidth-preserving techniques such as multicast transmission and powerful source coding algorithms. LÄS MER

  5. 9. Automatic Dense Reconstruction from Uncalibrated Video Sequences

    Författare :David Nister; KTH; []
    Nyckelord :Structure from Motion; Calibration; Match Moving; Reconstruction; Video; Computer Vision; Auto-calibration; Augmented Reality; Virtual Reality; Image-based Rendering; Visualisation; Camera Calibration; Motion Estimation;

    Sammanfattning : This thesis describes a system that completely automaticallybuilds a three-dimensional model of a scene given a sequence ofimages of the scene. The system also estimates the internalparameters of the camera and the poses from where the originalimages were taken. LÄS MER

  7. 10. Internet Video Transmission

    Författare :György Dan; Gunnar Karlsson; Viktória Fodor; Jean-Yves Le Boudec; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic control; MDC; FEC; Multicast streaming; Queuing theory; Telecommunication; Telekommunikation;

    Sammanfattning : The Internet has rapidly evolved from being a scientific experiment to a commercial network connecting millions of hosts that carries traffic generated by a large amount of applications with diverse requirements. Its architecture was however designed to enable efficient point-to-point delivery of bulk data, and can not provide statistical guarantees on the timely delivery of delay sensitive data such as streaming and real-time multimedia.
