  1. 11. Objective Perceptual Quality Assessment of JPEG2000 Image Coding Format Over Wireless Channel

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Författare :Bala Venkata Sai Sundeep Chintala; [2019]
    Nyckelord :Discrete Wavelet Transform DWT ; Image Coding Format; JPEG2000; Objective Perceptual Quality assessment; Quality of Experience QoE ;

    Sammanfattning : A dominant source of Internet traffic, today, is constituted of compressed images. In modern multimedia communications, image compression plays an important role. Some of the image compression standards set by the Joint Photographic Expert Group (JPEG) include JPEG and JPEG2000. LÄS MER

  3. 12. 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

  4. 13. Hardware Efficient Lossless Realtime Compression of Raw Image Data

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

    Författare :Måns Åhlander; Axel Jonsson; [2018]
    Nyckelord :Compression; Realtime; Video; Encoding; Bitrate; Technology and Engineering;

    Sammanfattning : When transmitting data it is often desired to lower the bitrate in the transmission. In video capture devices, such as video cameras, with a high resolution and high capturing rate the bitrate in the transmission is high and it is often desired to lower this bitrate. LÄS MER

  5. 14. Terrester fotogrammetri med Trimble V10 Imaging Rover - Mätosäkerhet och leveransformat : Test av Trimble V10 Imaging Rover och Trimble Business Center

    Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Samuel Laurell; [2017]
    Nyckelord :fotogrammetri; trimble v10; trimble business center; mätosäkerhet; punktmoln; panoramabilder; 3D-modeller; filformat;

    Sammanfattning : De vanligaste metoderna för insamling av geografisk information är idag genom GNSS och totalstation eller via traditionell fotogrammetri och laserskaning. Trimble V10 Imaging Rover är ett instrument som består av 12 kalibrerade kameror med skanningsfunktion. LÄS MER

  7. 15. Reducing Energy Consumption Through Image Compression

    Master-uppsats, Linköpings universitet/Datorteknik

    Författare :Mats Ferdeen; [2016]
    Nyckelord :Energy Consumption; Off-chip Memory; Image Compression; Structure From Motion; feature detection; camera trajectory; area error; block-wise image compression; JPEG; WebP;

    Sammanfattning : The energy consumption to make the off-chip memory writing and readings are aknown problem. In the image processing field structure from motion simpler compressiontechniques could be used to save energy. A balance between the detected features suchas corners, edges, etc., and the degree of compression becomes a big issue to investigate. LÄS MER
