Abstract: “The EMBDDED ZEROTREE WAVELET (EZW) algorithm, as presented by J. Shapiro, is a simple yet powerful algorithm, in which bit-streams are generated in order of their significance in containing the image information [1]. The original EZW algorithm scans the entire wavelet decomposed image, at a stroke, during each pass. This work presents a modified method for coding images using EZW method, which works on the principal of fragmentation. The proposed method takes the smallest unit cell, generated fr”
