Image compression using the 2-D wavelet transform . Compact Image Coding from Multiscale Edges - Dalbegue, Baras, al. Using the 2-D Wavelet Transform . The lossless compression of the signi cance map takes advantage of the fact that large output levels often appear in clusters. Unfortunately, the wavelet packet coecients fail to exhibit a self similar structure.
Correlations also exist across subbands.

In this section, we review a recently devised technique that has received much attention and which forms the basis for the compression system used in this thesis.
