  1. 1. 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. 2. Adaptive content-based sound compression

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Markus Gerard; Marcus Tedenvall; [2019]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Three different classification solutions for distinguishing events from non-events in surveillance audio are described and evaluated. The three compared methods are energy functions, Gaussian mixture modelling algorithms (GMM) and existing voice activity detectors (VAD). LÄS MER

  4. 3. Efficient Intra Prediction for the Next-Generation Video Compression Standard

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

    Författare :Hengyu Man; [2019]
    Nyckelord :;

    Sammanfattning : VVC (Versatile Video Coding) is a next-generation video compression standard.It is a potential successor to the MPEG-4/H.264 and High EfficiencyVideo Coding (HEVC)/H.265. LÄS MER

  5. 4. Visual Tracking with Deep Learning : Automatic tracking of farm animals

    Master-uppsats, KTH/Radio Systems Laboratory (RS Lab)

    Författare :Biwen Zhu; [2018]
    Nyckelord :Computer vision; Video tracking; Machine learning; Discriminative correlation filter; Compressed video; Bandwidth balancing; Network traffic; Dator vision; Video spårning; Maskininlärning; Diskriminerande korrelationsfilter; Komprimerad video; Bandbredd balansering; Nätverkstrafik;

    Sammanfattning : Automatic tracking and video of surveillance on a farm could help to support farm management. In this project, an automated detection system is used to detect sows in surveillance videos. This system is based upon deep learning and computer vision methods. LÄS MER

  7. 5. Intra-prediction for Video Coding with Neural Networks

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

    Författare :Paulina Hensman; [2018]
    Nyckelord :video coding; video compression; intra-prediction; ann; cnn; fcn; artificial neural networks; convolutional neural networks; fully connected networks; hevc; videokodning; videokomprimering; intra-prediktion; ann; cnn; fcn; hevc;

    Sammanfattning : Intra-prediction is a method for coding standalone frames in video coding. Until now, this has mainly been done using linear formulae. Using an Artificial Neural Network (ANN) may improve the prediction accuracy, leading to improved coding efficiency. LÄS MER
