In this Paper we introduce modified EZW algorithm for the purpose of image compression which seems to be an enhanced version compare to the existing algorithm. This algorithm is an extension of EZW algorithm given and analysed by Sharpiro's where we reduce the difficulty of EZW in transmitting the lower bit planes. In this paper, we include digital wavelet transformation and region of interest coding to modified EZW and hence make it more superior to EZW and SPIHT Algorithm and it is proved with the results.
