  1. 1. Compression of Large-Scale Aerial Imagery : Exploring Set Redundancy Methods

    Uppsats för yrkesexamina på grundnivå, Högskolan i Gävle/Datavetenskap

    Författare :Solvej Lüdeking; [2023]
    Nyckelord :Set redundancy; image compression; aerial imagery;

    Sammanfattning : Compression of data has been historically always important; more data is gettingproduced and therefore has to be stored. While hardware technology advances,compression should be a must to reduce storage occupied and to keep the data intransmission as small as possible. LÄS MER

  3. 2. 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

  4. 3. Massdigitalisering och kvalitativ digitalisering : En jämförelse av digitaliseringen på nationalbiblioteken i Norge och Sverige

    Magister-uppsats, Högskolan i Borås/Institutionen Biblioteks- och informationsvetenskap / Bibliotekshögskolan

    Författare :Christoffer Nilsson; [2009]
    Nyckelord :massdigitalisering; kvalitativ digitalisering; digitalisering; nasjonalbiblioteket; bevarande; kungl. biblioteket; tillgängliggörande; digitalisering av kulturarvet;

    Sammanfattning : The purpose of this thesis is to compare mass digitization and qualitative digitization, to see how the digitization process and the digitalized material differ. The study emanates from the mass digitization as it is performed at the National Library in Norway, and the qualitative digitization at the Royal Library in Sweden. LÄS MER

  5. 4. Image coding with H.264 I-frames

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Anders Eklund; [2007]
    Nyckelord :Image coding; H.264; I-frames; MPEG-4 Part 10; JPEG; JPEG2000; Data compression;

    Sammanfattning : In this thesis work a part of the video coding standard H.264 has been implemented. The part of the video coder that is used to code the I-frames has been implemented to see how well suited it is for regular image coding. LÄS MER

  7. 5. Hardware / Software co-design for JPEG2000

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Per Nilsson; [2006]
    Nyckelord :JPEG2000; Discrete Wavelet Transform; arithmetic coding; DSP processors; HW SW partitioning; ;

    Sammanfattning : For demanding applications, for example image or video processing, there may be computations that aren’t very suitable for digital signal processors. While a DSP processor is appropriate for some tasks, the instruction set could be extended in order to achieve higher performance for the tasks that such a processor normally isn’t actually design for.
