An Improved Image Compression Algorithm Based on Embedded Zerotree Wavelets Transform

Yanjun Liu and Zupeng Liu
Abstract—After analyzing the basic theory of embedded zerotree wavelet (EZW) coding algorithm, this paper brings forward an improved method which rounds down the wavelet coefficients and sets the coefficients appearing more frequent as zero, so as to reduce scan frequency in algorithm and save the storage space. Experimental results show that this algorithm improves the coding efficiency on the one hand; and on the other hand the quality of reconstructed image is also not significantly decreased.

Index Terms—Frequency, image compression, wavelet coefficients, embedded zerotree wavelets (EZW)
