  1. 16. Streaming Video over Unreliable and Bandwidth Limited Networks

    Författare :Hussein Aziz; Blekinge Tekniska Högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Streaming video; Mobile device; Frame splitting; Sub-frame crossing; Time Interleaving Robust Streaming; Region of Interest; Mean Opinion Score;

    Sammanfattning : The main objective of this thesis is to provide a smooth video playout on the mobile device over wireless networks. The parameters that specify the wireless channel include: bandwidth variation, frame losses, and outage time. LÄS MER

  3. 17. Data-Efficient Learning of Semantic Segmentation

    Författare :David Nilsson; Mathematical Imaging Group; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; semantic segmentation; embodied learning; active learning; semantic video segmentation; computer vision; deep learning;

    Sammanfattning : Semantic segmentation is a fundamental problem in visual perception with a wide range of applications ranging from robotics to autonomous vehicles, and recent approaches based on deep learning have achieved excellent performance. However, to train such systems there is in general a need for very large datasets of annotated images. LÄS MER

  4. 18. Understanding in Real-Time Communication : Micro-Feedback and Meaning Repair in Face-to-Face and Video-Mediated Intercultural Interactions

    Författare :Anna Jia Gander; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Communication; understanding; micro-feedback; meaning repair; intercultural communication; face-to-face FTF ; video-mediated communication VMC ; multimodal communi-cation; activity type; relevance; contextualisation; inference; information sharing; sense-making;

    Sammanfattning : Human communication is profoundly social. In social activities, it is not uncommon that people are understood in many different ways, which may have various consequences for social and interpersonal communication. LÄS MER

  5. 19. Human factors and wireless network applications : more bits and better bits

    Författare :Greger Wikstrand; Lars-Erik Janlert; Jerry Eriksson; Mark Högskolan Dalarna Ekonomi och samhälle Dougherty; Angela Sasse; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Human factors; Mobile multimedia; Access protocols; Computer network performance; Quality of service; Video conferencing; Computer games; Streaming video; Medium access control; Collision detection; Reliable multicast; Computer science; Datavetenskap;

    Sammanfattning : I avhandlingen beskrivs ett hypotetiskt system som kan användas av mobila användare, bland andra taxichaufförer, som exempelvis vill följa en viktig fotbollsmatch. Flera faktorer ställer till problem: Ibland står bilen still och föraren har inget annat att tänka på än matchen. LÄS MER

  7. 20. 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.
