  1. 1. Hierarchical structures and extended motion information for video coding

    Författare :Astrid Lundmark; John Håkon Husøy; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The thesis describes usage and generation of motion information in the field of video coding. Hierarchical structures for computation of this motion information are suggested. These hierarchical structures can be used also for other applications. LÄS MER

  2. 2. On error-robust source coding with image coding applications

    Författare :Tomas Andersson; Mikael Skoglund; Astrid Lundmark; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; source coding; channel coding; joint source-channel coding; multiple description coding; image coding; vector quantization; channel optimized vector quantization; Telecommunication; Telekommunikation;

    Sammanfattning : This thesis treats the problem of source coding in situations where the encoded data is subject to errors. The typical scenario is a communication system, where source data such as speech or images should be transmitted from one point to another. A problem is that most communication systems introduce some sort of error in the transmission. LÄS MER
