  1. 6. Content-aware Video Compression

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Vivek Subramanian; [2019]
    Nyckelord :region-of-interest; saliency map; bitrate; H.264; video com­pression; quantization offset;

    Sammanfattning : In a video there are certain regions in the image that viewers focus on more than others, which are called the salient regions or Regions­Of-Interest (ROI). This thesis aims to improve the perceived quality of videos by improving the quality of these ROis while degrading the quality of the other non-ROI regions of a frame to keep the same bitrate as would have been the case otherwise.

  4. 8. Video compression optimized for racing drones

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Datavetenskap

    Författare :Henrik Theolin; [2018]
    Nyckelord :;

    Sammanfattning : This thesis is a report on the findings of diifferent video coding techniques and their suitability for a low powered lightweight system mounted on a racing drone. Low latency, high consistency and a robust videostream is of the utmost importance. LÄS MER

  5. 9. Stable Communication Over a Wireless Network Under Heavy Load

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Mattias Eklund; Carl Nilsson Nyman; [2018]
    Nyckelord :wifi; lte; h.264; jpeg; 4g; Technology and Engineering;

    Sammanfattning : For our master's thesis we have worked with a company called Uniti to help them establish a system for communicating with their autonomous vehicle during a public demonstration. This included handling a video feed from the vehicle as well as assuring low latency for said feed. For the purposes of this thesis the targeted latency was below 200ms. LÄS MER

  7. 10. Offline H.264 encoding method for omnidirectional videos with empirical region-of-interest

    Uppsats för yrkesexamina på avancerad nivå, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Rémi Sormain; [2017]
    Nyckelord :virtual reality; 360 degree video; omnidirectional video; video encoding; gaze-contingency; panoramic virtual reality; region-of-interest;

    Sammanfattning : Panoramic virtual reality is an emerging technology that has recently gained the attention of both the research community and regular consumers. It allows the users to immerse themselves in omnidirectional videos with the help of a virtual reality headset : thanks to an increasing amount of affordable head-mounted-displays, any recent smartphone can offer a decent panoramic virtual reality experience.
