ABSTRACT The embedded zerotree wavelet algorithm (EZW) is a simple, yet remarkably effective, image compression algorithm, having the property that the bits in the bit stream are generated in order of importance, yielding a fully embedded code. The embedded code  As the communication channel in such places is very narrow, embedded image coding method that can provide progressive reconstruction is preferred so that the doctor can stop decod- ing based on the individual requirements at the decoding end

In recent years, much of the research activities in this area have been focused on the distribution of the wavelet coefficients of the image to achieve an embedded image coding . From the most famoustransmission at any time. 5) The maintenance of embedded coding of EZW makes the image transmit emerge gradually at the receiver terminal. All these show the potential of the proposed al- gorithm. Besides, its bit stream
