Due to its inherent time-scale locality characteristics, the discrete wavelet transform (DWT) has received considerable attention in signal/image processing. In the multistage DWT, coefficients are calculated recursively, and in addition to the wavelet decomposition stage, extra space is required to store the intermediate coefficients.

Image compression is concerned with minimization of the number of information carrying units used to represent an image. new domain decomposition based algorithms using image quality measures and study of various quality measures for gray scale image compression;
