Access is restricted indefinitely. ----- In this thesis, the previous research work on Spiral Architecture will be reviewed and the existing representation of SA will be improved to produce better performance. Additionally, the Fractal Image Compression (FIC) algorithm will be adapted to the Spiral Architecture for the first time using the improved representation. Comparisons will be carried out between the FIC performances on SA and square structure. The application of progressive FIC decoding and an FIC improved algorithm based on a difference image will also be discussed. The main purpose of the research work in this thesis is to introduce a potentially new direction of research in Fractal Image Compression by adopting it onto a hexagonal image structure - Spiral Architecture, so that others may bring forth valuable better results. The methods to be presented in this thesis can potentially be improved in various ways. This thesis develops and extends research results obtained by the author while preparing for the PhD since 2004. Most of the results have been previously published in sixteen research papers in refereed conference proceedings and journals.
