Here, we present a modi"cation of Shapiro's embedded zerotree wavelet algorithm (EZW) for image codec. Shapiro's technique is based on the wavelet transform and on the self-similarity inherent in images. In the EZW, the wavelet transform (WT) coe$cients, which provide a multiresolution representation of the image, are arranged according to their signi"cance across scales using a small symbol set (zerotree (ZT) coding). An analysis of the symbol entropy shows that better compression rates can be… CONTINUE READING
