    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. 3. Transcoding H.265/HEVC

    Magister-uppsats, Blekinge Tekniska Högskola/Sektionen för datavetenskap och kommunikation

    Författare :Sina Tamanna; [2013]
    Nyckelord :Transcoding; Transrating; High Efficiency Video Coding; HEVC H.265; Tree Sub-space Search;

    Sammanfattning : Video transcoding is the process of converting compressed video signals to adapt video characteristics such as video bit rate, video resolution, or video codec, so as to meet the specifications of communication channels and endpoint devices. A straightforward transcoding solution is to fully decode and encode the video. LÄS MER

  4. 4. Evaluation and Hardware Implementation of Real-Time Color Compression Algorithms

    Master-uppsats, Linköpings universitet/ElektroniksystemLinköpings universitet/Tekniska högskolan; Linköpings universitet/ElektroniksystemLinköpings universitet/Tekniska högskolan

    Författare :Amin Ojani; Ahmet Caglar; [2008]
    Nyckelord :Graphics Hardware; Color Compression; Image Compression; Mobile Graphics; Compression Ratio; Frame Buffer Compression; Lossless Compression; Golomb-Rice coding.;

    Sammanfattning : A major bottleneck, for performance as well as power consumption, for graphics hardware in mobile devices is the amount of data that needs to be transferred to and from memory. In, for example, hardware accelerated 3D graphics, a large part of the memory accesses are due to large and frequent color buffer data transfers. LÄS MER
