98EFFECTS OF RECOMBINING PROCESS FOR THE MULTIWAVELET FILTER BANK ONZEROTREE IMAGE CODINGK. AttakitmongcolSchool of Electrical Engineering, Institute of Engineering, Suranaree University of TechnologyAbstractWavelet-based  image  compression  using  zerotree structure has been shown to be a powerfulalgorithm. The coding scheme exploits the self-similarity of wa- velet coefficients across different scalesin the image representation using the wavelet transform. In multiwavelet case, since multiwavelets havemore than one scaling functions, the output from the analysis filter bank is a vector-valued sequence.Thus, to apply this coding scheme to multiwavelet filter bank, an additional step of recombining a vectorsequence to a scalar sequence must be applied. In this paper, we use different recombining methods tomultiwavelet filter bank and their effects on zerotree image compression are discussed.Published in the International Symposium on Communications and Information Technology (ISCIT), Chiangmai, November 14-16, 2001.
