M.Sc. Thesis Abstract

Digital medical image datasets are very large with Magnetic Resonance Imaging (MRI) and Computed Tomography (CT) accounting for a large proportion of the produced data. Medical image sequences like MRI contain interframe correlation as well as intraframe correlation. In principle, schemes like 3D-SPIHT which utilizes both interframe and intraframe correlation are expected to perform better in compression than those based on only intraframe correlation. The performance of 3D-SPIHT is varied by the condition of wavelet filter bank, decomposition structure, boundary extension, and etc. The contribution of this study is in finding the efficacy condition of 3D-SPIHT on medical image sequences.
