Paper Abstract

We propose a new approach to image compression based on the principle of Shapiro's embedded zero-tree wavelet (EZW) algorithm. Our approach, the efficient EZW (E-EZW), uses six symbols instead of the four used in the original Shapiro's algorithm to minimize the redundant symbols, and optimizes the coding by binary regrouping of the information. This approach can produce results that have a significant improvement over the peak signal-to-noise ratio and compression ratio obtained by Shapiro without affecting the computing time. These results are also comparable to those obtained using the set partitioning in hierarchical trees (SPIHT), set partitioning embedded block (SPECK), and JPEG2000 algorithms.
