  1. 1. Super Resolution Image Reconstruction using LWT

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Sivakrishna Padavala; Arifullah Baig Moghul; [2013]
    Nyckelord :Wavelets; Lifting Scheme; Super Resolution; Daubechies; Image Registration; SPIHT;

    Sammanfattning : Since over three decades, computers have been widely used for processing and displaying images. The ability to process visual information from a super resolution image can enhance the information present in the image. LÄS MER

  3. 2. Wavelet Based SPIHT Compression for DICOM Images

    Master-uppsats, Linnéuniversitetet/Institutionen för datavetenskap, fysik och matematik, DFM

    Författare :Iyyappan Dhasarathan; Vimal Rathinasamy; Tang Cui; [2011]
    Nyckelord :Image Compression; DICOM; SPIHT.;

    Sammanfattning : Generally, image viewers do not include the scalability for the image compressionand ecient encoding and decoding for easy transmission. They alsonever consider the specic requirements of the heterogeneous networks constitutedby the Global Packet Radio Service(GPRS), Universal Mobile TelecommunicationSystem(UMTS), Wireless Local Area Network(WLAN) and DigitalVideo Broadcasting(DVB-H).

  4. 3. Implementering av realtidsvideolänk med MPEG- och wavelet-teknik

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Karl Heijdenberg; Thomas Johansson; [2004]
    Nyckelord :Technology; Image coding; data compression; DCT; MPEG; OpenGL; real time transmission; simulator; SPIHT; transform theory; UDP; wavelets; TEKNIKVETENSKAP;

    Sammanfattning : At Saab Aerosystems, situated in Linköping Sweden, there is a presentation and manoeuvre simulator simulating the fighter jet JAS-39 Gripen. This flight simulator is called PMSIM. In this thesis we study how to transfer sensor images generated by PMSIM to other simulators or desktop computers. LÄS MER

  5. 4. Compression of Medical Image Stacks using Wavelets and Zero-Tree Coding

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Erik Sjöblom; [2002]
    Nyckelord :Technology; Wavelets; 3D-coding; Zero-Tree coding; SPIHT; TEKNIKVETENSKAP;

    Sammanfattning : The use of computers for handling image data in the healthcare is growing. The amount of data produced by modern image generating techniques, such as CT and MR, is vast. The amount of data might be a problem from a storage point of view or when the data is sent over a network. LÄS MER
