  1. 6. Hur upplevd videokvalitet påverkas av upplösning och bitrate

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

    Författare :Christoffer Eriksson; Jimmy Mäkinen; [2021]
    Nyckelord :Upplevd videokvalitet; bitrate; upplösning; videokomprimering; bildartefakter.;

    Sammanfattning : Streaming is currently the main method used to watch videos, and with this a significant portion of all Internet traffic is occupied by streaming. In order to efficiently store and transfer this large quantity of data, compression is necessary for the streaming services. LÄS MER

  3. 7. Speeding up a mixed reality application: A study of two encoding algorithms

    Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Jesper Elgh; Ludvig Thor; [2020]
    Nyckelord :;

    Sammanfattning : Mixed reality (MR) or augmented reality (AR) is a way of combining the digital world with the real world. It is utilized in a number of different applications. The mobile devices of today may not always provide sufficient processing power to handle these kind of applications. LÄS MER

  4. 8. L4S in 5G networks

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

    Författare :Davide Brunello; [2020]
    Nyckelord :Low Latency Low Loss Scalable Throughput; Self-Clocked Rate Adaptation for Multimedia; 5G; Latency-critical application;

    Sammanfattning : Low Latency Low Loss Scalable Throughput (L4S) is a technology which aims to provide high throughput and low latency for the IP traffic, lowering also the probability of packet loss. To reach this goal, it relies on Explicit Con- gestion Notification (ECN), a mechanism to signal congestion in the network avoiding packets drop. LÄS MER

  5. 9. Characterizing Video Compression Using Convolutional Neural Networks

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

    Författare :Sebastian Emmot; [2020]
    Nyckelord :Neural Networks; Image Analysis; Video Analysis; Compression; Deep Learning;

    Sammanfattning : Can compression parameters used in video encoding be estimated, given only the visual information of the resulting compressed video? If so, these parameters could potentially improve existing parametric video quality estimation models. Today, parametric models use information like bitrate to estimate the quality of a given video.

  7. 10. 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.
